Question

Based on polarity, can you please predict whether the following compounds will be solution in water (polar solvent) or cyclohexane (nonpolar solvent) NaNO_3 Vegetable Oil A solution contains 30 m Eq/L of Cl and 20 mE/L of PO_4^3, if Na^+ is the only cation in the solution, what is the Na^+ conc. in mEq/L? At 20 degree C/the solubility of KCI is 34g/100g of water. Answer the following questions: a) How much of the KCI will dissolve in 250 g of water? b) Is the solution saturated or unsaturated if we try to dissolve 102 g of KCI into 250 g of water? Circle all possible ionic compounds that will be soluble in water: a) AgBr

Explanation / Answer

30 meq/L of Cl-

20 meq/L of PO43-

1 meq/L of Na+ = 3 meq/L of PO43-

20 meq/L of PO43- = 20/3 meq/L of Na+

1 meq/L of Cl- = 1 meq/L of Na+

30 meq/L of Cl- = 30 meq/L of Na+

total Na+ = (20/3 + 30 ) meq/L of Na+ = 36.67 meq/L of Na+ Answer
