Question

Which salt obtained from calcium hydroxide and nitric acid?
Which salt obtained from zinc and hydroxide and sulphuric acid?
Which salt obtained from potassium hydroxide and sulphuric acid?
Which salt obtained from sodium carbonate and nitric acid?
Which salt obtained from magnesium and sulphuric acid?

Answer 1

Answer

1) $Ca(OH)_{2} + HNO_{3}$ ⇒  $Ca(NO_{3}) _{2} + 2H_{2} O$

   Therefore, salt formed is Calcium Nitrate

2) $Zn(OH)_{2} + H_{2} SO_{4}$ ⇒ $ZnSO_{4} + H_{2}O$

   Therefore, salt formed is Zinc sulphate

3) $K(OH)_{2} + H_{2} SO_{4}$ ⇒ $KSO_{4} + H_{2}O$

   Therefore, salt formed is Potassium sulphate

4) $NaCO_{3} + HNO_{3}$ ⇒ $NaNO_{3} + CO_{2} + H_{2}O$

   Therefore, salt formed is Sodium Nitrate

5)$Mg + H_{2} SO_{4}$ ⇒ $MgSO_{4} + H_{2}$ ↑

 Therefore, salt formed is Magnesium sulphate
