1. A factory employee drops a 100 L concentrated sulfate acid canister, which is full of pH, into a neutral pool containing 900 L of water, and all the sulphate acid in the canister mixes into the pool.

a) How many kg of pure NaOH should be added to neutralize the water in the pool.

b) To remove sulfate ions formed as a result of ionization of sulfate acid as BaSO4 and remove it from water b) How many kg of pure BaCl2 salt should be added to water?

NOTE: Concentrated sulfate acid is 98% by mass.
