Q)
$124\;g$ of mix containing $NaHCO_3,AlCl_3,KNO_3$ requires 500 ml,8% w/w $NaOH$ soln. $[ dNaOH =1.8 gm/ml]$ for complete neutralisation . On heating same amt of mix , it shows loss in weight of 18.6 gm. Calculate % composition of mixture by moles.Weak base formed does not interfere in reaction. Assume $KNO_2$ doesn't decompose under given conditions
