20 gmof a mixture of NaCl and NaOH exactly requires 7.3gm HCL for complete reaction. The mass percent of NaCl in the original mixture is:

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)

1.0 gm of a mixture of CaCO_3 and NaCl reacts completely with 120 ml of N/10 HCI. The percentage of NaCI in the mixture is:

In the mixture of NaHCO_(3) and NaCO_(3) , volume of a given HCl required is x ml with phenolphathalein indicator and further y mL is required with methyl orange indicator. Hence volume of HCl for complete reaction of NaHCO_(3) present in the original mixture is

2.1 g of a mixture of NaHCO_3 and KCIO_3 required 100 " mL of " 0.1 HCl for complete reaction. Calculate the amount of residue that would be obtained on heating 2.2 g of the same mixture strongly.
