Answer 2

Answer:

1. Acids react with most metals to form a salt and hydrogen gas. ... For example, zinc metal reacts with hydrochloric acid producing zinc chloride and hydrogen gas.
2. Salts are prepared by reacting an acid with a metal or a base, such as a metal carbonate, hydroxide or oxide. The acid provides the non-metal ion for the salt, e.g. chloride or sulphate or nitrate ions. The metal or base provides the metal ion for the salt, e.g. sodium or copper.

4. Acetic acid can be used to increase the acidity (and lower the pH) of food products as well as improve the organoleptic quality by giving the product an acid flavor, such as salt and vinegar chips. Acetic Acid is also a popular preservative as it stops bacterial growth in dressings, sauces, cheese, and pickles
5. Bee venom is slightly acidic and contains formic acid - but the major finding is that it is not the acidity of bee venom that causes the pain and the swelling, but rather lots of other nasty ingredients.
6. Sodium bicarbonate (IUPAC name: sodium hydrogen carbonate), commonly known as baking soda (especially in North America and New Zealand) or bicarbonate of soda, is a chemical compound with the formula NaHCO3.
