Sodium carbonate (na2co3) is used to neutralize the sulfuric acid spill. how many kilograms of sodium carbonate must be added to neutralize 2.01×103 kg of sulfuric acid solution?

of sodium carbonate must be added to neutralize of sulfuric acid solution.

Further Explanation:

Stoichiometry:

Theamountof species present in the reaction is determined with the help of stoichiometryby the relationship between reactants and products. It is used to determine the moles of a chemical species when moles of other chemical species present in the reaction is given.

Balanced chemical reaction between sodium carbonate and sulphuric acid is as follows:

According to stoichiometry of reaction, one mole of reacts with one mole of to produce one mole of , one mole of   and one mole of . So stoichiometric ratio between and is 1:1.

The formula to calculate number of moles of is as follows:

                                            …… (1)

Substitute for mass of and 98.079 g/mol for molar mass of in equation (1).

Since one mole of reacts with one mole of , 20493.7 moles of reacts with 20493.7 moles of .

The formula to calculate mass of is as follows:

               …… (2)

Substitute 20493.7 mol for moles of and 105.9888 g/mol for molar mass of in equation (2).
