Question

Aqueous solutions of magnesium chloride and sodium hydroxide react to produce solid magnesium hydroxide and aqueous sodium chloride.

Answer 1

Answer:

2MgCl+ 2NaOH--> 2MgOH + 2 NaCl

Answer 2

DOUBLE DISPLACEMENT REACTION -

• The reaction in which positive and negative ions of two ionic compounds exchange with each other to form new compounds.
• It involves the formation of an insoluble compound known as a precipitate or gas or some soluble compounds.
• The reaction usually takes place in an aqueous solution.
• The precipitate forms settle at the bottom of the beaker and may or may not be colorless.
• In the reaction of magnesium chloride with sodium hydroxide, magnesium hydroxide formed is a precipitate in the solution of sodium chloride.
• The reaction involved is -

                                           $MgCl_2 + NaOH$ → $Mg(OH)_2 + NaCl$

• The precipitate of Magnesium hydroxide is white in color formed by the release of energy.
