19.3 Slightly Soluble Recall solubility rules These things are soluble, everything else is insoluble Well, there is no completely insoluble, it’s just that very, very little dissolves Dissolution reaction (look for ions): CoCO 3 ( s ) Co 2+ ( aq ) + CO 3 2- ( aq )

Equilibrium CoCO 3 ( s ) Co 2+ ( aq ) + CO 3 2- ( aq ) K sp = 1.0 * 10 -10 What is equation of K in this reaction? If 42 g of CoCO 3 ( s ) is dissolved in 2.45 L of water, what is the concentration of Co 2+ and CO 3 2- ions in the water? What if 255 g of CoCO 3 ( s ) is dissolved?

Another example If 23 g of Ag 2 S where K sp = 8 * 10 -48 is dissolved in 1.5 L of water what is the concentration of Ag + and S 2- ions? What is the pH of 55 g of Fe(OH) 2 K sp = 4.1 * 10 -15 dissolved in 1.2 L of water?

More Examples What would put more IO 3 - ions in 1.0 Liter of water: 0.15 moles of Ba(IO 3 ) 2 K sp = 1.5 * 10 -9 0.15 moles of AgIO 3 K sp = 3.1 * 10 -8 “S” = moles of the salt dissolved
