Study Notes
Acid Salts and Their Solutions
- Acid salts produce acidic solutions when dissolved in a solvent due to the presence of hydrogen ions (H+).
- Greater electrical conductivity in acid salt solutions is attributed to their ionization in water, resulting in free-moving ions.
Ammonia and Hydrochloric Acid
- The main species formed upon half-neutralization of ammonia in hydrochloric acid is ammonium chloride (NH4Cl).
Leavening Acids in Food Products
- Common leavening acids include cream of tartar (potassium bitartrate) and phosphoric acid, often used in baking to produce carbon dioxide gas.
Interaction of Acidic and Alkaline Salts
- Mixing an acidic salt, like cream of tartar, with an alkali salt such as baking soda (sodium bicarbonate) results in an acid-base reaction that produces carbon dioxide gas, causing dough to rise.
