Question

write the equation of softening and hard water contain magnesium salt with sodium carbonate​

Answer 1

Equation of softening and hard water contain magnesium salt with sodium carbonate​:

• The Hard water has large amount of dissolved minerals. $Na_2CO_3$ is the chemical formula for sodium carbonate.
• The reaction between the "magnesium sulfate and sodium carbonate" gives a precipitate of magnesium carbonate, {$MgCO_3$} and sodium sulfate    {$Na_2SO_4$} as byproduct.
• The Sodium (Na) has +1 charge and Chlorine (Cl) has -1 charge and they become together to form the aquoeous NaCl.
• The magnesium (Mg) has +2 charge and the polyatomic ion $CO_3$ has -2 charge, they become together to form the solid $MgCO_3$ which is in solid form because of carbonate's solibility rule.

The equation of softening and hard water contain magnesium salt with sodium carbonate​ is follows:

                             $MgCl_2+Na_2CO_3 \rightarrow 2NaCl+MgCO_3$
