Due to rounding, the Ksp value you calculate may be slightly different, but it should be close. Transcript A compound's molar solubility in water can be calculated from its K value at 25C. The solubility (by which we usually mean the molar solubility) of a solid is expressed as the concentration of the "dissolved solid" in a saturated solution. The reaction of weakly basic anions with H2O tends to make the actual solubility of many salts higher than predicted. When the can is closed, the gas is under more pressure, and there are lots of bubbles because a lot of the gas is dissolved. The equation for the Ksp of Ca (OH)2 is the concentration [Ca2+] times the concentration [OH-] taken to the second power, since the OH- has a coefficient of 2 in the balanced equation. To better organize out content, we have unpublished this concept. of the fluoride anions. A compound's molar solubility in water can be calculated from its K. What would you do if you were asked to find the ppm of the cu2+ ion or the OH- ion? From this we can determine the number of moles that dissolve in 1.00 L of water. Before any of the solid Fourth, substitute the equilibrium concentrations into the equilibrium

If the concentration of fluoride in fluoridated drinking water is 1 \times 10^{-5} M and the calcium iron concentration in b. So less pressure results in less solubility, and more pressure results in more solubility. First, determine
calcium two plus ions, and since there's a coefficient of one in the balanced equation, that's the concentration So we're going to leave calcium fluoride out of the Ksp expression. Heres an example: The $K_s_p$ value of $Ag_2SO_4$ ,silver sulfate, is 1.4$10^{}^5$. For insoluble substances like silver bromide (AgBr), the molar solubility can be quite small. You do this because of the coefficient 2 in the dissociation equation. This is because we were given a molarity for how much Ba3(PO4)2 dissolved, as opposed to a gram amount. Solution: 1) The chemical equation: Ca(OH) 2 Ca 2+ + 2OH 2) The K sp expression: . it will not improve the significance of your answer.). For very soluble substances (like sodium nitrate, NaNO3), this value can be quite high, exceeding 10.0 moles per liter of solution in some cases. So 2.1 times 10 to the is in a state of dynamic equilibrium between the dissolved, dissociated,
