The solubility of O2 in water is 0.590 g/L at an oxygen pressure of around 15.5 atm. What is the Henry's law constant for O2?

The Henry's constant for oxygen gas is

Explanation:

To calculate the molar solubility, we use the equation given by Henry's law, which is:

where,

= Henry's constant = ?

= molar solubility of oxygen gas =

= partial pressure of oxygen gas = 15.5 atm

Putting values in above equation, we get:

Hence, the Henry's constant for oxygen gas is

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
