A solution contains mixture of H_(2)SO_(4)" and " H_(2)C_(2)O_(4). 25 ml of this solution requires 35.5 ml of N/10 for neutralization and 23.45 ml of N/10 KMnO_(4) for oxidation, calculate (i) Normality of H_(2)C_(2)O_(4) " and " H_(2)SO_(4) (ii) Strength of H_(2)C_(2)O_(4)" and " H_(2)SO_(4)

In some foam-type fire extinguishers, the reactants are Al_2 (SO_4)_3 (aq) and NaHCO_3 (aq). When the extinguisher is activated, these reactants are allowed to mix producing Al(OH)_(3(s)) and CO_(2(g)) . The Al (OH)_3 - CO_2 foam extinguishes the fires . Addition of Na_2 CO_3 to a solution of an oxide in ester produces CO_2 . This experiment indicates that :
