Question

Part C

The steps to balancing a neutralization reaction when given a verbal description can be summarized as follows:

Write the chemical formulas for the reagents.

Write the chemical formulas for the products.

Balance each element on each side of the reaction arrow by adding coefficients to the reactants and products.

The antacid Brioschi, which has been used to relieve heartburn, is mainly sodium bicarbonate. Predict the products, then write the balanced neutralization reaction for the antacid Brioschi in the stomach where the main acid present is hydrochloric acid, HCl.

Express your answer as a chemical equation.

Element name Common ions Polyatomic ion name Ion Sodium Na+ Nitrate NO3? Potassium K+ Hydroxide OH? Lithium Li+ Bicarbonate HCO3? Calcium Ca2+ Carbonate CO32? Magnesium Mg2+ Sulfate SO42? Aluminum Al3+ Sulfite SO32? Chlorine Cl? Chromate CrO42? Bromine Br? Dichromate Cr2O72? Fluorine F? Phosphate PO43?

The salt, lithium fluoride, is composed of lithium ( Li + ) cation(s) and fluoride (F ) anion(s). 5. The salt, calcium nitrate, is composed of calcium (Ca2) cation/s) and nitrate (NO3) anion(s)

Explanation / Answer

A)

1)

2 lithium cations and 1 chromate anion

2)

2 Fe+3 cations and 3 chromate anions

3)

3 Co+2 cations and 2 phosphate anions

4)

1 Li+ cation and 1 F- anion

5)

1 Ca+2 cations and 2 N03- anions

B)

the reactions are

1 CaC03 + 2 HCl ---> 1 CaCl2 + 1 H20 + 1 C02

1 Mg(OH)2 + 2 HCl ---> 1 MgCl2 + 2 H20

C)

the reaction is between NaHCO3 and HCl

so

HCl + NaHC03 ---> NaCl + H20 + C02
