What is observed when 2 mL of dilute hydrochloric acid is added to 1 g of sodium
carbonate taken in a clean and dry test tube? Write chemical equation for the reaction
involved.

Text Solution

Verified by Experts

Hydrochloric acid decomposes sodium carbonate to form sodium chloride and liberates
`CO_(2)` gas which turns lime water milky.
`underset ("carbonate") underset("Sodium")(Na_(2)CO_(3)(s)) + underset ("acid")underset ("Hydrochloric")(2HCl(aq)) underset()(rarr) underset("chloride")underset("sodium")(2NaCl(aq)) + underset("Water")(H_(2)O(l))+ underset ("dioxide")underset("Carbon")(CO_(2)(g)`
