Alka-seltzer® is an antacid. one of its active ingredients is nahco3. write out an equation to show how alka-seltzer® neutralizes stomach acids (hcl).

NaHCO3 + HCl --> NaCl + CO2 + H2O

Explanation:

NaHCO3 which is an acidic salt because of the replaceable H+ (Bronste lowry acid), by definition acid dissociates in water to release a proton.

NaHCO3 dissociates in water to give Na+, H3O+ and HCO3-

Stomach acid which is HCl also dissociates in water to give H3O+ and Cl-

The H3O+ and HCO3- combines briefly to form a weak carbonic acid almost immediately, which then further dissociates to form H2O and CO2. CO2 is burped out from the mouth.

Na+ and Cl- combines to form NaCl in water which is a table salt solution.
