Question 1 Report

Which of the following solutions will give a precipitate with dilute tetraoxosulphate (V) acid? l. Lead (ll) trioxonitrate (V) solution ll. Barium chloride solution lll. Sodium chloride solution
Answer Details
Barium chloride solution (ll) will give a precipitate with dilute tetraoxosulphate (V) acid. This is because barium chloride is a salt of barium and chloride ions, while tetraoxosulphate (V) acid is a solution of sulphate ions and hydrogen ions. When barium chloride solution is added to dilute tetraoxosulphate (V) acid, the barium ions react with the sulphate ions to form a white insoluble solid called barium sulphate. This is the precipitate that is formed. Lead (ll) trioxonitrate (V) solution and sodium chloride solution will not give a precipitate with dilute tetraoxosulphate (V) acid.
