1. Aqueous solutions of acids are (electrolytes, nonelectrolytes), meaning that they conduct an electrical current. Some acids are (weak, strong) electrolytes because they ionize completely in water, yielding a great many ions. Other acids are (strong, weak) electrolytes that exist primarily in a non-ionized form when dissolved in water. 2. Acids have a (sour, bitter) taste. Lemons, vinegar, and sour candies all contain acids. 3. Acids change the color of certain acid-base indicators. Two common indicators are litmus and phenolphthalein. Blue litmus turns (red, blue, colorless) in the presence of an acid, while phenolphthalein turns (colorless, red, blue).
