What is the general outcome of an acid-base neutralization reaction?

• A. A salt and a gas are formed
• B. Water and a salt are formed
• C. A metal deposits
• D. An acid dissolves another acid

Answer: (B)

Neutralization is a proton-transfer reaction between an acid and a base in water. The hydrogen ion from the acid meets the hydroxide ion from the base to form water. The remaining ions from the acid and base pair up to make a salt. So, the general outcome is water and a salt. For example, mixing an acid like HCl with a base like NaOH gives NaCl (a salt) and H2O (water). Other possibilities, like forming a gas, metal deposits, or acids reacting with other acids, don’t fit the typical neutralization pattern because they involve different kinds of chemical changes.
