3. An acid turns_______litmus _______.

An acid turns litmus red. This is because litmus is a pH indicator that changes color in the presence of acids or bases. In acidic solutions, litmus paper turns red, indicating the presence of an acid. However, if the acid is diluted or weak, the litmus paper may only turn slightly red or pink. On the other hand, litmus paper remains blue in neutral or basic solutions.

4. ACIDS ARE ____________.

Acids are soluble in water because they are composed of molecules that can easily dissociate in water, forming hydrogen ions (H+) and anions. These hydrogen ions then interact with water molecules, creating a solution in which the acid is evenly distributed throughout the water. This solubility allows acids to easily mix and react with other substances in aqueous solutions.
