Question

Which of the following does not react with a dilute $H_2{SO}_4$ solution?

• A. $Na{NO}_3$
• B. ${Na}_{2}S$
• C. ${Na}_2{PO}_4$
• D. ${Na}_2{CO}_3$
• E. $NaOH$

Answer 1

The correct option is A $Na{NO}_3$

$NaN{O}_3$ is derived from a strong base & a strong acid; therefore it is neutral. The other chemicals are basic being derived from a strong base & weak acid.There is no reaction because there is nothing insoluble to form. The sodium, hydrogen, sulfate and nitrate ions all stay dissolved in solution. Therefore, there will be no precipitate and the concentrations of the ions will remain the same. So does the pH.
