Caustic (optics) In optics, a caustic or caustic network[1] is the envelope of light rays reflected or refracted by a curved surface or object, or the projection of that envelope of rays on another surface.[2] The caustic is a curve or surface to which each of the light rays is tangent, defining a boundary of an envelope of rays as a curve of concentrated light.[2] ...

- Sodium hydroxide (NaOH), also known as lye and caustic soda, is an inorganic compound. It is a white solid and highly caustic metallic base and alkali of sodium which is available in pellets, flakes, granules, and as prepared solutions at different concentrations. Sodium hydroxide forms an approximately 50% (by mass) saturated solution with water. Sodium hydroxide is soluble in water, ethanol, and methanol. This alkali is deliquescent and readily absorbs moisture and carbon dioxide in air.

Wet chemistry Graduated cylinders and beakers filled with chemicals. Wet chemistry is a form of analytical chemistry that uses classical methods such as observation to analyze materials. It is called wet chemistry since most analyzing is done in the liquid phase. Wet chemistry is also called bench chemistry since many tests are performed at lab benches.

hydrate Hydration definition, any of a class of compounds containing chemically combined water. In the case of some hydrates, as washing soda, Na 2 CO 3 ⋅10H 2 O, the water is loosely held and is easily lost on heating; in others, as sulfuric acid, SO 3 ⋅H 2 O, or H 2 SO 4 , it is strongly held as water of constitution. to combine chemically with water.

- 1 A precipitate is a solid formed in a solution as the result of a chemical reaction. 2  The reaction with baking soda solution and calcium chloride produced a white precipitate (calcium carbonate). 3  Another common precipitate is soap scum. In the chemical reaction with baking soda solution and calcium chloride, breaking bonds between the atoms of sodium bicarbonate (baking soda) requires energy. 2  It also takes energy to break the bonds between the ions in calcium chloride.

- Water base cleaners or cleaner intended to be used in water. Opposite of acid; same as alkaline A strong alkaline; the term, when used alone, usually refers to caustic soda (sodium hydroxide). Caustic soda is the alkali used in the manufacture of many cleaning products. It is also used as a neutralizing agent for acids.

Irritating Chemicals (Caustics) Rinse the mouth with a little water or milk to rid it of any caustic that may still be there. Look for symptoms of injury including visible burns in the mouth or the signs and symptoms listed above. If there is any sign of injury, take your child to the emergency department immediately. NEVER make your child vomit.

Spent caustic The contaminants have consumed the majority of the sodium (or potassium) hydroxide and thus the caustic liquor is spent, for example, in one common application H2S (gas) is scrubbed by the NaOH (aqueous) to form NaHS (aq) and H2O (l), thus consuming the caustic.

- A caustic chemical has a primary damage effect that lasts for 1d4 rounds and a residual damage effect that lasts for 2d4 rounds thereafter. The dose for an acid or base is six fluid ounces. armour takes damage only during the primary effect. While rare, these fluids are actually fairly cheap.

Lye Lye, or caustic soda, is a mixture of sodium hydroxide and water. This strong alkaline compound is used sparingly in baking due its dominate properties. While stronger solutions of lye have been made famous for making soap and other cleaners, food-grade lye is a much milder solution. It is commonly used as a preservative or softening agent.

Lime (material) Burning (calcination) converts them into the highly caustic material quicklime (calcium oxide, CaO) and, through subsequent addition of water, into the less caustic (but still strongly alkaline) slaked lime or hydrated lime (calcium hydroxide, Ca(OH) 2), the process of which is called slaking of lime.hen the term is encountered in an agricultural context, it probably refers to agricultural lime. Otherwise it most commonly means slaked lime, as the more dangerous form is usually described more specifically as quicklime or burnt lime.
