Acids, Bases and Salts #1

Alternate Acid

• H⁺ donor

• H^- acceptor

• H⁺ neutralizer

• H⁺ stabilizer

Arrhenius Base

• a substance that produces hydroxide ions (OH^-) as the only negative ion in solution

• a substance that donates protons (H⁺) in solution

• a substance that accepts electrons in a chemical reaction

Acidic Solution

• pH less than 7

• pH equal to 7

• pH greater than 7

• pH equal to 14

pH scale

• concentration of H⁺ ion can be expressed using the pH scale

• The pH scale is used to measure temperature.

• The pH scale indicates the amount of dissolved oxygen in water.

• The pH scale is a measure of the salinity of a solution.

Neutral Solution

• pH equals 7

• pH equals 14

• [H₃O⁺] > [OH^-]

• [H₃O⁺] < [OH^-]

Acid-Base Indicators

• substances that change colors when exposed to solutions of different pH values

• substances that neutralize acids and bases

• substances that increase the pH of a solution

• substances that are always colorless in any solution

Conjugate Acid-Base Pairs

• an acid and a base that differ by only 1 hydrogen ion

• two acids that have the same molecular formula

• a base and a salt that react in a neutralization reaction

• an acid and a base that are both strong

Arrhenius Acid

• a substance that produces hydrogen ions (H⁺) as the only positive ion in solution

• a substance that increases the concentration of hydroxide ions (OH^-) in solution

• a substance that can donate a proton (H⁺) to another substance

• a substance that reacts with metals to produce hydrogen gas
