Identify A and B: `CaSO_4+ Na_2CO_3 to A+ B`

Identify A, B and C: NaHSO_3 + H_2SO_4 to A+ B+ C(gas)

Complete the reactions : CaSO_4 + Na_2CO_3 to ….. + Na_2SO_4

Identify the type of reaction Na_2CO_3 + 2H_2O to 2NaOH + H_2CO_3

In the mixture of (NaHCO_3 + Na_2CO_3) , volume of HCI required is x mL with phenolphthalein indicator and y mL with methly orange indicator in the same titration. Hence, volume of HCI for complete reaction of Na_2CO_3 is : (a) 2x (b) y (c) x/2 (d) (y-x)

Balance the following equation : NaHCO_3 to Na_2CO_3 + H_2O + CO_2 .

500 " mL of " a solution contains 2.65 g of Na_2CO_3 and 4 g of NaOH . 20 " mL of " this solution titrated each time against (N)/(10)H_2SO_4 . Find out the titre value if (a). Methyl orange is taken as an indicator (b). Phenolphthalein is taken as indicator.
