1. Suppose it takes 33.69mL OF 0.005123 M EDTA to titrate 25.00mL of hard water solution

a) What is the concentration expressed as molarity of Ca2+ of hard water ions in the solution?

b) If the metal ions in the hard water all came from CacO3, how many grams of CaCO3 would be in 1.000L of the solution (in other words, determine g CaCo3/L)

C) Convert g CaCO3/L calculated in (b) to mg CaCO3/L. (This is equivalent to ppm)

2. Rank the  following alkal iearth metals  in their order of solubility starting from the highest. Ba2+,CA2+.Mg2+, Sr2+.How does this trend compare with the order of the alkaline earth metals on the periodic table?
