Question

What is the word equation for the reaction that takes place between sodium hydroxide and copper sulphate solutions?

Answer 1

Hint: When acid i.e. HCl is added to the diamine silver chloride, it forms the curdy white precipitates of the silver halide which is insoluble along with the protonation of amine. Now you can easily write the chemical reaction.

Complete answer:
First, we should know what a chemical reaction is. The reaction in which the reactants react with each other to form two or more products is known as the chemical reaction. The reactants are written on the left hand side and the products are written on the right-hand side and there is an arrow from left to the right symbolizing a complete chemical reaction.
Example: consider the general reaction as:
$A+B\to C+D$
Here, A and B are the reactants and C and D are the products and the arrow indicates the direction in which the chemical reaction occurs.
Now considering the statement as;
When the base sodium hydroxide is made to undergo reaction with the copper sulphate solution, it results in the formation of the copper hydroxide and sodium sulphate. The chemical reaction is supposed to take place as;
$2NaOH(aq)+CuS{{O}_{4}}(aq)\to N{{a}_{2}}S{{O}_{4}}(aq)+Cu{{(OH)}_{2}}(s)$
It is a double displacement reaction in which the positive and the negative ions of the two reactants involved in the chemical reactions exchange their positions.

Note:
After writing the equation check whether the no of moles of each atom are same on both the sides or not and if not, then balance the chemical reaction because it helps to conserve the mass of that very atom/substance or the compound.
