- Acids and bases are substances which change the balance of hydrogen and hydroxide ions in water. Both are divided into two categories - strong acids or bases which ionize completely in water, and weak acids or bases which ionize only partially in water.

- I. Acids *Acids are ionic compounds (a compound with a positive or negative charge) that break apart in water to form a hydrogen ion (H +). *The strength of an acid is based on the concentration of H + ions in the solution. The more H+ the stronger the acid.

Acids, Bases, & the pH Scale An acid is a substance that donates hydrogen ions. Because of this, when an acid is dissolved in water, the balance between hydrogen ions and hydroxide ions is shifted. Now there are more hydrogen ions than hydroxide ions in the solution. This kind of solution is acidic.A base is a substance that accepts hydrogen ions. When a base is dissolved in water, the balance between hydrogen ions and hydroxide ions shifts the opposite way. Because the base soaks up hydrogen ions, the result is a solution with more hydroxide ions than hydrogen ions.This kind of solution is alkaline.o be more precise, pH is the negative logarithm of the hydrogen ion concentration: pH = −log [H+]. The square brackets around the H + automatically mean concentration to a chemist. What the equation means is just what we said before: for each 1-unit change in pH, the hydrogen ion concentration changes ten-fold.

Arrhenius Acid-Base Theory Lewis Acid-Base Concept. The Lewis theory classifies a substance as an acid if it acts as an electron-pair acceptor and as a base if it acts as an electron-pair donor. Other ways of classifying substances as acids or bases are the Arrhenius concept and the Bronsted-Lowry concept. substance is classified as a base if it produces hydroxide ions OH(-) in water. This way of defining acids and bases works well for aqueous solutions, but acid and base properties are observed in other settings.

- An acid (from the Latin acidus/acēre meaning sour) is a chemical substance whose aqueous solutions are characterized by a sour taste, the ability to turn blue litmus red, and the ability to react with bases and certain metals (like calcium) to form salts.Aqueous solutions of acids have a pH of less than 7.he Arrhenius definition defines acids as substances which increase the concentration of hydrogen ions (H +), or more accurately, hydronium ions (H 3 O +), when dissolved in water. The Broensted-Brønsted lowry definition is an: expansion an acid is a substance which can act as a proton. donor

Acid Non-aqueous acids are usually formed when an anion (negative ion) reacts with one or more positively charged hydrogen cations. A lower pH means a higher acidity, and thus a higher concentration of positive hydrogen ions in the solution. Chemicals or substances having the property of an acid are said to be acidic.

In pure water, there are an equal number of hydrogen ions and hydroxide ions. The solution is neither acidic or basic.

Chemistry for Kids Acids and bases are two special kinds of chemicals. Almost all liquids are either acids or bases to some degree. Whether a liquid is an acid or base depends on the type of ions in it. If it has a lot of hydrogen ions, then it is an acid. If it has a lot of hydroxide ions, then it is a base.

Chemical Properties of Acids and Bases Chemical Properties of Acids and Bases. As acids and bases are highly corrosive and reactive substances it is important to understand their reaction and responses on substances commonly found around us. It helps us to understand the outcomes of using them in daily life. Let see the different acids and bases.ome common acids that are found in laboratories are Hydrochloric acid (HCl), Sulphuric acid (H2SO4) and Nitric acid (HNO3). Some of the lesser used acids are Acetic acid (CH3COOH), Hydrofluoric acid (HF), Carbonic acid (H2CO3).

Acid Aqueous Arrhenius acids have characteristic properties which provide a practical description of an acid. Acids form aqueous solutions with a sour taste, can turn blue litmus red, and react with bases and certain metals (like calcium) to form salts. The word acid is derived from the Latin acidus/acēre meaning sour.

Definitions of Acids and Bases Tutorial Definitions of Acids and Bases. 1  Many substances can be classified as either acids or bases based on their properties. 2  The definition of what an acid or a base is, is dependent on the chemical system being studied.  Arrhenius acid produces hydrogen ions (H+ or protons). Arrhenius base produces hydroxide ions (OH-).

- Substances that can donate hydrogen ions, thus increasing [H + ], are acids. Strong acids have pH much lower than 7. Molecules that accept hydrogen ions, thus decreasing [H + ], are bases and have pH higher than 7. Some examples are given in the graph.

What is an acid? What is a base? An acid is a compound or a substance that increases the concentration of hydrogen ions. It is also said to be a proton donor. When an acid is dissolved in water, a solution is formed with a hydrogen ion activity greater than in pure water.AND A base is thought of as a substance which can accept protons or any chemical compound that yields hydroxide ions (OH-) in solution.n short, an acid is a compound that can give up a hydrogen ion (a proton, H+) in solution. A base is a compound that can accept a proton. If you're looking at chemical equations, the acid will be the compound with more hydrogen atoms.

General Chemistry/Types of chemical reactions Acid-Base Neutralization [edit]. In simple terms, an acid is a substance which can lose a H + ion (i.e. a proton) and a base is a substance which can accept a proton. When equal amounts of an acid and base react, they neutralize each other, forming species which aren't as acidic or basic.

General Chemistry/Reactions of Acids and Bases An anhydride is a substance that does not contain water. More specifically, it is a substance that reacts with water to form an acid or base. Anhydrides are usually in the form of a gas that dissolves into water and reacts to form an acid or base. They can also be solids that will react with water.

Acids and Bases By the 1884 definition of Svante Arrhenius (Sweden), an acid is a material that can release a proton or hydrogen ion (H +). Hydrogen chloride in water solution ionizes and becomes hydrogen ions and chloride ions. If that is the case, a base, or alkali, is a material that can donate a hydroxide ion (OH-).

Acids, Bases and Salts Some bases are water soluble and some bases are water insoluble. Water soluble bases are also called alkalis. Like acids, alkalis' strength is determined by its ability to be ionized into metal and hydroxide OH-ions.cids are substances made of a hydrogen ion and non-metal ions. They have the following properties: 1  They dissolve in water producing a hydrogen ion H 2  + , They have a sour taste, 3  Strong ones are corrosive, 4  Their pH is less than 7.
