In an experiment the following solids were provided to form three students; Ca(NO₃)_2(s),NaH₂PO_4(s); Mg(OH)Cl_(s) and Fe(NH₄)₂(SO₄)₂. 6H₂O. They were then told to dissolve the
given solids in differently in 20ml of water.
(a) Classify the given salts accordingly
(b) (i) Explain the process which takes place when FeCl₃ is dissolved in water
(ii) A student placed a moist litmus paper on the product in (i) above. State and explain the observation made

Answers

a)- Acid salts NaH₂PO_4(S)
-Basic salts – Mg (OH) CL_(s)
-Normal salts – Ca (NO₃)_2(S)
-Double salt – Fe(NH₄)₂ (SO₄)₂ 6H₂O

b) i) Hydrolysis – Reaction of water with a compound to form at least two products
ii) Moist litmus paper turns red due to the HCL gas produced
