Question

question 9 - 1 point
a solution of a compound in water conducts electricity, turns litmus red, and has a sour taste. what compound might be in the solution?
select the correct answer below:
nahco₃
mg(oh)₂
c₃h₅(cooh)₃
nh₃

Explanation:

• \(NaHCO_3\) (sodium bicarbonate) is a basic salt. It does not turn litmus red.
• \(Mg(OH)_2\) (magnesium hydroxide) is a base. Bases turn litmus blue, not red.
• \(NH_3\) (ammonia) forms a basic solution in water ( \(NH_3 + H_2O

ightleftharpoons NH_4^++OH^-\) ) and turns litmus blue.

• \(C_3H_5(COOH)_3\) (citric acid) is an acid. Acids conduct electricity (due to ionization in water, \(C_3H_5(COOH)_3

ightleftharpoons C_3H_5(COO^-)_3 + 3H^+\) ), turn blue litmus red, and have a sour taste.

Answer:

\(C_3H_5(COOH)_3\)
