1.24 grams of magnesium phosphate tribasic dissolved in 1 L of lemon juice. What is the Ksp of the magnesium phosphate tribasic in lemon juice at room temperature?

a. 2.52e^-10
b. 7.56e^-9
c. 1.26e^-11
d. 6.42e^-10

The solubility product of magnesium phosphate tribasic is

Explanation:

To calculate the molarity of solution, we use the equation:

Given mass of magnesium phosphate = 1.24 g

Molar mass of magnesium phosphate = 262.85 g/mol

Volume of solution = 1 L

Putting values in above equation, we get:

The equation for the ionization of the magnesium phosphate is given as:

Expression for the solubility product of will be:

We are given:

Putting values in above expression, we get:

Hence, the solubility product of magnesium phosphate tribasic is

the major pests we deal with are insects, weeds and fungal diseases. a pesticide is a product, whether organic or chemical, used to kill the target pest. there are other techniques gardeners should use that can prevent the severe infestations that make the use of pesticides necessary

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
