Describe the pH scale and what it measures??? The pH scale measures how acidic or basic a substance is. The pH scale ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic. A pH greater than 7 is basic. The pH scale is logarithmic and as a result, each whole pH value below 7 is ten times more acidic than the next higher value. For example, pH 4 is ten times more acidic than pH 5 and 100 times (10 times 10) more acidic than pH 6. The same holds true for pH values above 7, each of which is ten times more alkaline (another way to say basic) than the next lower whole value.

- The scale of pH measurements goes from 0 (the most acidic) to 14 (the most basic). Pure water is right smack in the middle with a pH of 7, which is neutral. The pH scale is logarithmic, meaning. that each one-unit change in pH actually represents a 10-fold change in acidity. For example, lemon juice at pH. 2.0 is ten times more acidic than vinegar at pH 3.0. pH is a measurement of the amount of H+ ions in a. solution. Pure water is considered neutral at a pH of 7 because the number of H+ ions is exactly the same as the. number of OH- (hydroxide) ions produced when these dissociate in water.

- When substances dissolve in wa-ter they produce charged molecules called ions. Acidic water contains extra hydrogen ions (H+) and basic water contains extra hydroxyl (OH-) ions. pH is measured on a scale of 0 to 14. Neutral water has a pH of 7. Acidic water has pH values less than 7, with 0 being the most acidic.

What is true of acids? Here's why: An acid has a pH below 7. At exactly pH 7 a solution is neutral. Any pH above 7 is basic. Electrolytes are compounds that dissociate (separate) in solutions. Strong acids/bases are strong electrolytes. Weak acids/bases are weak electrolytes.So, answer C is incorrect because it could be true or false depending upon what kind of acid you have. Acids want to get rid of H+ ions (it's part of what characterizes them). Bases have an affinity for H+ ions and want to pick them up.ere's why: An acid has a pH below 7. At exactly pH 7 a solution is neutral. Any pH above 7 is basic. Electrolytes are compounds that dissociate (separate) in solutions. Strong acids/bases are strong electrolytes.

pH Treatment Acidic and basic are two extremes that describe a chemical property chemicals. Mixing acids and bases can cancel out or neutralize their extreme effects. A substance that is neither acidic nor basic is neutral. The pH scale measures how acidic or basic a substance is. The pH scale ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic. A pH greater than 7 is basic. The pH scale is logarithmic and as a result, each whole pH value below 7 is ten times more acidic than the next higher value. For example, pH 4 is ten times more acidic than pH 5 and 100 times (10 times 10) more acidic than pH 6.

- 1 When universal indicator is added to a solution, the color change can indicate the approximate pH of the solution. 2  Acids cause universal indicator solution to change from green toward red. 3  Bases cause universal indicator to change from green toward purple.tudents may say that the color of the solution in well 2 is yellow or yellow-green. Then have students assign a number for pH. Tell students that if the color in the well seems to be between two colors on the chart, they should assign a pH value between the two.

pH Pure water is neutral. When an acid is dissolved in water, the pH will be less than 7. When a base, or alkaline, is dissolved in water, the pH will be greater than 7. A solution of a strong acid, such as hydrochloric acid, at concentration 1 mol dm −3 has a pH of 0. A solution of a strong alkaline, such as sodium hydroxide, at concentration 1 mol dm −3, has a pH of 14.

- Acid - Base Indicators: The most common method to get an idea about the pH of solution is to use an acid base indicator. An indicator is a large organic molecule that works somewhat like a  color dye. Whereas most dyes do not change color with the amount of acid or base present, there are many molecules, known as acid - base indicators , which do respond to a change in the hydrogen ion concentration. Most of the indicators are themselves weak acids. The most common indicator is found on litmus paper.

How do you make a solution mare acidic or basic (is HCl and NaOH used?)? Solutions are defined as Basic if their pH is higher than 7 and acidic if less than 7. pH is an indication of the consentration of H+ ions the higher the concentration the lower the pH so to make a solution more basic you would decrese the H+ ion concentration by adding some OH ions (anything with OH-shoud do it). just now. Report Abuse. Add an acid if you want to make it more acidic, add a base if you want to make it more basic. HCl is an acid so it would make a solution more acidic, NaOH is a base so it would make a solution more basic. There's plenty of other acids and bases that could be used though.

- In solutions where the hydrogen ions exceed the concentration of hydroxide ions, the pH falls below 7.0 and is an acid. In solutions where the hydroxide ions exceed the concentration of hydrogen ions, the pH rises above 7.0 and is a base.   The pH of a substance tells if it's an acid, neutral, or a base.

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.
