Which is least soluble in water?

Which is least soluble in water?

Options

  1. ANa2 S\mathrm{Na}_2 \mathrm{~S}
  2. BMgS\mathrm{MgS}
  3. CMgCl2\mathrm{MgCl}_2
  4. DNaCl\mathrm{NaCl}

Correct answer

B. MgS\mathrm{MgS}

Step-by-step solution

MgS\mathrm{MgS} is most covalent so it is least soluble in water.
