Question
Antacid tablets contain a variety of bases such as NaHCO3, MgCO3, CaCO3, and Mg(OH)2. Only NaHCO3 has appreciable solubility in water.

In parts 1 - 4, write a balances net ionic equation, including states of matter, for the reaction of each antacid with aqueous HCl. Then in part 5 choose the best statement to describe antacids.
 
A net ionic equation will not include spectator ions, but must include states of matter.
Write the net ionic equation for NaHCO3 + HCl
 
Write the net ionic equation for MgCO3 + HCl
 
Write the net ionic equation for CaCO3 + HCl
 
Write the net ionic equation for Mg(OH)+ HCl
 
Choose the best answer to explain how insoluble substances can act as effective antacids.

Choose one:
Even as a solid, the antacid will react with H+ to neutralize the acid
A small portion of the solid dissolves and neutralizes the acid
The volume of the solid decreases the acid concentration, causing the pH to rise.
