Assuming a soap to be pure sodium stearate, give balanced equation to illustrate the following:?

a) Why its solutions are alkaline:
b) Its reaction with Ca+2 in hard water:


a) CH3-(CH2)16-COONa+HCl=CH3-(CH2)16-COOH + NaCl

b) 2CH3-(CH2)16-COONa+CaCO3=(CH3-(CH2)1... +Na2CO3
- the second reaction explains why soap doesn't make as many "bubbles" in hard water
hope this two reaction are enough for you.
