Question

a compound X is bitter to taste it is a compound of sodium and reacts with dilute HCl to produce brisk effervescence due to a colourless and odourless gas Y which turns limewater milky due to the formation of Z when excess of CO2 is passed milkyness disappears due to the formation of P. identify X, Y ,Z and P.write the equation involved in formation of Y,Z,P

Answer 1

1. X is Sodium carbonate( Na2CO3).
2) Y is CO2 gas.
3) z is calcium carbonate
4 )P is calcium hydrogen carbonate.
the balanced equation is :
Ca(OH)2+ CO2 ----> H2O +CaCO3
CaCO3 + CO2 + H2O----> Ca(HCO3)2

Answer 2

Answer:

X – Sodium Carbonate

Y – Carbon Dioxide

Z – Calcium Carbonate

P - Calcium Hydrogen Carbonate
