Textbook Problem

Balance the equation for the following precipitation reaction, and then write the net ionic equation. Indicate the state of each species (s, , aq, or g).

Ni(NO 3 ) 2 +Na 2 CO 3 NiCO 3 +NaNO 3

Expert Solution
Interpretation Introduction

Interpretation:

The given equation has to be balanced and net ionic equation for this reaction should be written.

Concept introduction:

Most of the ionic compounds are soluble in water, very few of the ionic compounds are sparingly soluble, and some of the ionic compounds are insoluble in water.  When it is soluble in water ions gets separated in the solution.

Soluble compounds in water

Almost all the salts of Na+, K+, NH4+, salts of nitrate (NO3-), chlorate (ClO3-), Perchlorate (ClO4-), Acetate (CH3CO2-) are soluble.

Almost all the salts of Cl-, Br-, I-(halides) are soluble. But some of the halides are (Ag+, Hg22+, Pb2+) are insoluble.

Salts of F- are soluble.  But some of the fluoride salt of Mg2+, Ca2+, Sr2+, Ba2+, Pb2+ are insoluble.

Salts of sulfate (SO42-) are soluble.  But sulfates of Ca2+, Sr2+, Ba2+, Pb2+, Ag+, are insoluble.

Insoluble compounds in water:

Most of the salts of carbonate (CO32-), phosphate (PO43-), Oxalate (C2O42-), Chromate (CrO42-), sulfide (S2-) are insoluble but some of the salts of NH4+, alkali metal cations and BaS are soluble.

Most of the metal hydroxides and oxides are insoluble in water bit some of the alkali metal hydroxides, Ba(OH)2and Sr(OH)2 are soluble in water.

Explanation of Solution

The given compound is sodium phosphate and calcium chloride which is soluble in water. In this reaction Na+ and Ca2+ cations exchange the anions (Cl- and PO32-) to give sodiumchloride and calcium phosphate.

  

Balance the equation,

Balance the sodium atom in the given equation, when balancing the equation, we should not alter the subscripts and we can change coefficients.

There are two sodium atoms in the left side and one sodium atoms in the right side. Therefore two molecule of sodium nitrate is added to right side of reaction.  Therefore the balanced equation is given below.

  

Therefore the balanced equation is given below.

  

Almost all the salts of Na+, K+, NH4+, salts of nitrate (NO3-), chlorate (ClO3-), Perchlorate (ClO4-), Acetate (CH3CO2-) are soluble
