Short Answer TypeExplain the following phenomenon by means of balanced equations:
(i) When exhaling is made through a tube passing into a solution of lime water, solution becomes turgid.
(ii) The turbidity of the above solution.
(iii) eventually disappears when continued exhaling is made through it.
(i) Exhaling means passing CO2 gas through lime water Ca(OH)2. CaCO3 is formed which makes solution turbid.
.
(ii) When exhaling is continued, CO2 converts CaCO3 into Ca(HCO3)2 which is colourless. Therefore turbidity disappears.
(iii) Upon heating the solution, Ca(HCO3)2 is converted back to CaCO3 which gives turbidity to the solution
