Question

a solution of a compound in water conducts electricity, turns litmus red, and has a sour taste. what compound might be in the solution?
nahco₃
nh₃
mg(oh)₂
c₃h₅(cooh)₃

Explanation:

• \(NaHCO_3\) (sodium bicarbonate) is a salt and its solution is basic (turns litmus blue).
• \(NH_3\) (ammonia) forms a basic solution (turns litmus blue) when dissolved in water.
• \(Mg(OH)_2\) (magnesium hydroxide) is a base and its solution is basic (turns litmus blue).
• \(C_3H_5(COOH)_3\) (citric acid) is an acid. Acids conduct electricity (due to ionization in water), turn blue litmus red, and have a sour taste.

Answer:

\(C_3H_5(COOH)_3\)
