A dilute aqueous solution of N a 2 S O 4 is electrolysed using platinum electrodes. The products at the anode and cathode are: The products at the anode and cathode are: View Solution

(a) Dilute nitric acid is generally considered a typical acid except for its reaction with metals. In what way is dilute nitric acid different from other acids when it reacts with metals? (b) Write the equation for the reaction of dilute nitric acid and conc. nitric acid with copper.

Sodium nitrate on reaction with ___ (concentrated/dilute) sulphuric acid produces nitric acid. View ...

Zinc reacts with dilute nitric acid to give zinc nitrate and hydrogen gas. Zinc + nitric acid → Zinc nitrate + hydrogen Z n ( s ) + 2 H N O 3 ( a q ) → Z n ( N O 3 ) 2 ( a q ) + H 2 ( g )

(i) Dilute nitric acid with copper. (ii) Sodium hydrogen carbonate is added to nitric acid. (b) State whether the following statement is correct or incorrect. Correct if it is incorrect. Nitric acid is tasteless. [3 MARKS]

When zinc reacts with very dilute nitric acid it produces N H 4 N O 3 4 Z n + 10 H N O 3 → 4 Z n ( N O 3 ) 2 + N H 4 N O 3 + 3 H 2 O Hence option A is correct.

Nitric acid H N O 3 is a strong oxidising agent. The Hydrogen gas produced during the reaction with metal gets oxidized to H 2 O, hence no hydrogen gas is produced. Instead, it evolves nitric oxides such as N O 2, N O etc.

The reaction of zinc with dilute and concentrated nitric acid, respectively, produces N 2 O and N O 2. a . 4 Z n + 10 H N O 3 ( d i l . ) → 4 Z n ( N O 3 ) 2 + N H 4 N O 3 + 3 H 2 O

The products obtained when very dilute nitric acid (HNO 3) reacts with magnesium are and hydrogen gas.

The metal which reacts with very dilute nitric acid to evolve hydrogen gas is. View Solution. Q3.
