| An acid is a chemical substance any of various typically water soluble and sour compounds that are capable of reacting with a base to for a salt, that redden litmus paper, that evolve hydrogen on reaction with various metals, that in water solution yield hydrogen ions, and that have hydrogen containing molecules or ions able to give up a proton to a base or that are substances able to accept and unshared pair of electrons from a base. An alkaline is a chemical compound that neutralizes or effervesces with acids and turns litmus blue; it’s a corrosive substance. Two similarities between acid and alkaline is that they are sour and they each changes litmus paper into another color than it was originally was. The differences between an acid and an alkaline are that acids have a Ph scale of any numbers below 7 and alkaline is from any numbers that is 7 or greater. I have searched three examples of acids they are: Sulfuric, Nitric, Citric acid. Sulfuric acid is used in alcohol, paper, glue, rubber, paints, dyes, fertilizers, and plastics. Nitric acid is mostly used in explosives, fertilizers, dyes, perfumes, nitrate salts, and nitro glycerin. And citric acid is most commonly used in foods, A preservative- it is added to food to keep them preserved and protects against mold. It is also used in photography- It allows the pictures to lighten in a dark room. Also have searched on Three examples of alkaline they are as follows: NaOH (Sodium Hydroxide), NH3 (Ammonia) and KOH (Potassium Hydroxide). : NaOH is used for mostly to clean. Like drains. NH3 is mainly used for vehicle fuel, textile or even a poison treatment. And last but not least KOH, this alkali is used for food preparation, medical test and etc. I have learned that mostly everything around us is contained by either alkaline or acid.
