Question 1 Report

Na2CO3(g) + 2HCl(aq) → 2NaCl(aq) + H2O(l) + CO2(g)

How many moles of sodium trioxocarbonate (IV) are there in a 25 cm3 solution which required 10cm3 of 0.05 mol dm-3 hydrochloric acid solution to neutralize it?

Answer Details
C A V A C B V B = a b

0.05 × 10 C B × 25 = 2 1

50CB = 0.5

CB =  0.5 50 = 5 100

= 0.01
