A 0.5187-gram sample of calcium chloride (CaCl2;MW 110.98g/mol) was dissolved in 300. mL of water. What is the molality of the solution? (Assume the density of water is 1.00g/ml)
To test a water sample for lead, 25 grams of sodium chloride is dissolved into 100.0 mL of the water. If no precipitation occurs, the concentration of lead(II) ions in the water is below what concentration?
4. Sodium hydroxide dissolved in water is considered an electrolyte. Magnesium chloride dissolved in water is also considered an electrolyte. If these two solutions were mixed together, would a precipitate form? If so, what is the formula of that precipitate? Would the resulting solution still be considered an electrolyte? Why or why not?
