Calculate the mass of pure sodium chloride that will yield enough hydrogen chloride gas to neutralize 25cm3 of 0.5M potassium trioxocarbonate (V) solution
from the reaction above, 2 moles of HCl reacts 1 mole of K2CO3.
This means that 0.025 moles of HCl reacts 0.0125 moles of K2CO3.
from the reaction above, 2 moles of NaCl produces 2 moles of HCl.
This means that 0.025 moles of NaCl reacts with 0.025 moles of H2SO4.
1 mole of NaCl is 58.5g
therefore, 0.25 moles of NaCl is 14.625g
therefore, 14.625g of NaCl will yield enough HCl to neutralize 25cm3 of 0.5M K2CO3.
