The solubility of Ag 2 SO 4 in water at 25°C is 0.0155 m. What is K sp for Ag 2 SO 4 ?

hey everyone. So here it says a saturated solution of iron three hydroxide has a molecular weight of one oh 6.87 g per mole and it contains 5.89 times 10 to the negative 10 moller of hydroxide ions here we need to calculate our liability product constant, otherwise known as K. S. P. For Iron three hydroxide within water. Alright, so remember anytime they're giving us Ks. P. For a compound that means we're dealing with an ionic solid. So here we have iron three solid and here we're gonna. So it's dissociation how it breaks up into ions. It breaks up into one iron three ion plus three hydroxide ions here. Since we're dealing with the sai ability of an ionic solid, we're dealing with an ice chart. Remember in an ice truck we ignore solids and liquids, so are solid reacting to be ignored. Initially we have zero of both of these ions. But remember your coefficients here will dictate your change. So this will be plus one X. Or plus X. And this would be plus three x plus X plus three X. Now he here stands for equilibrium at equilibrium, hydroxide ion concentration is equal to three X. But also we're told that it is equal to 5.89 times 10 to the -10 moller. So we can make those two equal to one another by doing this. This will help us to isolate the value of X, Divide both sides by three. And we see that X equals so we going down here X equals 1.96 times 10 to the negative 10 moller. This is important because if I know what X. Is, I can figure out K. Sp now K. S. P. Is equal to products. Overreact ints my reacting as a solid so I can ignore it. So que sp just equals products. The coefficient in front of hydroxide also gives us the power of three. So at equilibrium this was equal to ax. This was equal to three X. three. x cubed is three to the third which is 27 and X cubed is X cubed. Then this becomes 27 x to the 4th. We found out what X is. So I'll plug that in. So 1.96 times 10 to the -10 to the 4th. So here you would do 1.96 times 10 to the negative 10 to the 4th 1st Which will give me 1.476 times 10 to the -39. And to that answer, I'd multiply it by 27 Which gives me 3.985. 2 times 10 to the -38 Which you couldn't round to 3.99 or so, times 10 to the negative 38 as our final answer. So this would be the K. S. P. Or sigh ability product constant for iron three. Hydroxide
