A is a 0.5M KOHl solution, while B is a solution obtained after 1dm' of 0.75M HCl reacted with 30g of a powdered sample of limestone" soil. (a) Put B into the burette and titrate it against 20.00cm or 25.00cm portions of solution A in a conical flask using methyl orange as indicator. Repeat the procedure two or more times to obtain consistent titre values. Record and tabulate your results and hence calculate your average titre. (b) From your table and the information given above, calculate the; (i) The initial moles of the HCl solution (B). (ii) Moles of the KOH reacting. (iii) Final moles of B (excess). (iv) Moles of HCl that reacted with the soil sample. (v) Moles of CaCO3 in the soil sample. (vi) Mass of the CaCO3 in the soil sample. (vii) Percentage of CaCO; in the soil sample.
