Astudent wants to dissolve the maximum amount of caf2 (ksp = 3.2 x 10^−11) to make 1 l of aqueous solution.
(a) into which of the following solvents should she dissolve the salt?
i) pure water
ii) 0.01 m hf
iii) 0.01 m naoh
iv) 0.01 m hcl
iv) 0.01 m ca(oh)2
(b) which would dissolve the least amount of salt?

The answer to A would be iv) 0.01 M HCL, but I'm not sure what the answer to part B is. Hope this helps.

Explanation:

nacl is added to the aqueous of what? ? in order to get a proper answer you have to specify the exact composition of the aqueous solution.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
