Identifying a Base Among Solutions

Very Easy General Chemistry Acids And Bases

In chemistry, acids and bases play a vital role in various biological and chemical processes. Acids are substances that can donate a proton (H⁺ ion) and increase the concentration of hydronium ions (H₃O⁺) in a solution, while bases are substances that can accept a proton or produce hydroxide ions (OH^-) when dissolved in water.

Consider the following solutions:

Solution 1: Hydrochloric acid (HCl)
Solution 2: Sodium hydroxide (NaOH)
Solution 3: Ammonium chloride (NH₄Cl)
Solution 4: Sodium bicarbonate (NaHCO₃)

Based on your understanding of acids and bases, which of the following solutions is classified as a base?

Hydrochloric acid (HCl)

Sodium hydroxide (NaOH)

Ammonium chloride (NH<sub>4</sub>Cl)

Sodium bicarbonate (NaHCO<sub>3</sub>)
