Question

question 2 of 10 which of the following is an acid? a. lioh (lithium hydroxide) b. koh (potassium hydroxide) c. h₂so₄ (sulfuric acid) d. nh₃ (ammonia)

Explanation:

Acids are substances that release hydrogen ions ($H^+$) in solution. Lithium hydroxide ($LiOH$) and potassium hydroxide ($KOH$) are bases as they release hydroxide ions ($OH^-$). Ammonia ($NH_3$) is a base which can accept a proton. Sulfuric acid ($H_2SO_4$) dissociates in solution to release hydrogen ions.

Answer:

C. $H_2SO_4$ (Sulfuric acid)
