The correct option is this: ACIDS DISSOLVE IN WATER TO PRODUCE A SOLUTION THAT REACT WITH METALS TO PRODUCE HYDROGEN GAS.
An acid refers to a chemical specie that is capable of donating protons or hydrogen ion and is also capable of accepting electrons. An acid can be described either as strong or weak acid depending on its degree of dissociation in water. A strong acid dissociates completely while a weak acid dissociates partially. When an acid dissociates in water, it yields cation and anions. When an acid react with metal, hydrogen gas and salt are usually formed.
