Answer 1

Answer #1

Addition of CaCl₂ to a sample of water increases the hardness of water (it causes permanent hardness).

Basically, the soap molecules react with such hardness causing ions to form insoluble precipitate. This results in wastage of soap as the soap molecules are consumed by these ions and more amount of soap needs to be added to have the same cleansing effect as compared to when such ions were absent.

In this case, after the addition of CaCl₂, a significant fraction of soap present in the solution will precipitate by forming insoluble calcium salt. This will result in lesser amount of soap available to form suds.

So, the answer to the question should be: c) fewer suds.

Feel free to ask for any further clarifications.

All the best.
