Question

Sodium hydroxide neutralises acid. H+ + OH– → H2O In a 11 000 dm3 sample of an aqueous solution, the concentration of acid, [H+ ], is 1.26 × 10– 3mol dm–3. Which mass of solid sodium hydroxide neutralises the acidA 0.0214 g B 0.0504 g C 236 g D 554 g

Answer 1

Answer:

$Conc.of[H+]=Conc.of[OH−]</p><p>mole of sodium hydroxide must be same as the conc of acid.</p><p>mass of sodium hydroxide is=554g$
