Solution: Which compound below does not form a gas when reacted with hydrochloric acid?a. NaHCO3b. Ba(NO3)2c. K2SO3d. MgSe. All of the above will form a gas when reacted with HCl.

Problem

Which compound below does not form a gas when reacted with hydrochloric acid?

a. NaHCO3

b. Ba(NO3)2

c. K2SO3

d. MgS

e. All of the above will form a gas when reacted with HCl.


Solution

Write the reactions of each compound with HCl and determine the compound that will NOT produce gas when reacted with HCl

Recall that HCl is one of the common strong acids that dissociate as H+ and Cl-

a. NaHCO3

  • NaHCO3 is considered an amphoteric compound which means it can act as a base or an acid
