One litre solution of alkali ( NaOH ) is prepared by dissolving impure solid of alkali which contian 5% Na_(2) CO_(3) and 8% CaCO_(3) and 10%NaCl. A 10ml portion of this solution required 9.8 ml of a 0.5 M H_(2)SO_(4) solution for neutralization. Calculate weight of alkali dissolved initially gm eq. of Na_(2) CO_(3) + gm eq. of CaCO_(3) + gm eq. of NaOH = gm of H_(2) SO_(4)
