Acid, Base and Salt

  1. 1. A substance that releases H+ ions in an aqueous solution Acids have a sour taste. Acids react with metals. Acids contain hydrogen. Acids turns blue litmus red.
  2. 2. An acid is a chemical substance whose aqueous solutions are characterized by a sour taste, the ability to turn bluelitmus red, and the ability to react with bases and certain metals (like calcium) to form salts. Common examples of acids include hydrochloric acid , acetic acid sulfuric acid (used in car batteries), and tartaric acid As these examples show, acids can be solutions or pure substances, and can be derived from solids, liquids, or gases. Strong acids and some concentrated weak acids are corrosive, but there are exceptions such as carboranes and boric acid.
  3. 3. A substance that releases OH- ions in an aqueous solution Bases usually taste bitter. Bases feel slippery. Bases contain hydroxide ions. Strong bases are also poisonous and corrosive the skin.
  4. 4. A base is a chemical species that donates electrons or hydroxide ions or that accepts protons. Sodium hydroxide is an example of a base.
  5. 5. Salts are ionic compounds that result from the neutralization reaction of an acid and a base. Salts can appear to be clear and transparent. Salts can elicit all five basic tastes e.g., salty, sweet. Solid salts do not conduct electricity. Salts are formed by a chemical reaction.
  6. 6. Salts exist in many different colors, for example:
  7. 7. Common salt-forming anions (parent acids in parentheses where available) include: Common salt-forming cations include:
