A mixture containing equimolar amounts of `Ca(OH)_(2)` and `Al(OH)_(3)` requires `0.5` L of `4.0` M HCl to react with it completely. Moles of the mixture are :

100 ml aqueous solution containing equimolar mixtrue of Ca(OH)_(2) and Al(OH)_(3) requires 0.5 litre of 4M HCl for complete neutralisation. Molarity of Ca(OH)_(2) , in the original solution is :

10.0 g of a mixture of BaO and CaO require 100 mL of 2.50 M HCl to react with it completely. Amount of BaO in the mixture is (At mass Ca = 40, Ba = 137, O = 16)

2 mole, equimolar mixture of Na_(2)C_(2)O_(4) and H_(2)C_(2)O_(4) required V_1 L of 0.1 M KMnO_4 in acidic medium for complete oxidatiion. The same amount of the mixture required V_2 L of 0.1 M NaOH for neutralization. The ratio of V_(1) " to "V_2 is x:y, then the value of x + y is (x and y are integers)

10 g of a mixture of BaO and CaO requires 100cm^(3) of 2.5 M HCl to react completely. The percentage of calcium oxide in the mixture is approximately (Given : molar mass of BaO= 153)

10 g of a mixture of BaO and CaO requires 100 cm^(3) of 2.5M HCl to react completely. The percentage of calcium oxide in the mixture is approximately (Given molar mass of BaO = 153, CaO = 56)

One gram equimolecular mixture of Na_(2)CO_(3) and NaHCO_(3) is reacted with 0.1 M HCl. The milliliters of 0.1 M HCl required to react completely with the above mixture is :
