Question

A compound X of sodium forms a white powder. It is constituent of baking powder and used in
some antacids. When heated it gives a compound Y which is anhydrous and absorbs water to
become hydrated salt? When dissolved in water it forms a strong base and a weak acid Z.
Identify X, Y and Z by writing equations.​

Answer 1

Explanation:

x= sodium hydrogencarbonate heated give a compound Y= sodium carbonate Z=sodium carbonate is weak acid. NaHCO3----heat ---Na2CO3 + CO2 +H2O

Answer 2

$X = NaHCO_{3}$

$Y = Na_{2} CO_{3}.10 H_{2} O$

Nature of Y = alkaline

$Z = NaOH$
