As the temperature O decrease, stay constant increases, decreases deceases, decreases increases, increases the solubility of O2 in water

The solubility of carbon dioxide in water at 25°C and 1 atm is 0.034 mol/L. What is its solubility in (mol/L) under condition of a partial pressure of 19 psi?

A common practice in cooing is the addition of salt to boiling water. The boiling point of elevation is described by the equation, which is similar to freezing point depression equation but uses a different constant. imagine that your friend tells you that this is done in order to raise the temperature of the boiling water. If 1.50 kg (1.50L) of water is boiling at 100 degrees celsius how much NaCl (molar mass= 58.44g/mole) would need to be added to the water to increase the boiling point by 1 degree Celsius? Does your friend's explanation make sense?

Which of the following compounds is most soluble in water? Assume that all Ksp values are for identical conditions. a) zinc hydroxide, Ksp = 7.7x10–17 b) calcium phosphate, Ksp = 2.2x10–33 c) magnesium fluoride, Ksp = 7.4x10–11 d) lithium carbonate, Ksp = 8.2x10–4

Henry's law constant for transferring 02 from air into water, at room temperature, mmol liter – atm • - is 1.3 Given that the partial pressure of O2 in the atmosphere is 0.21 atm, the concentration of dissolved oxygen (mg/liter) in water in equilibrium with the atmosphere at room temperature is (Consider the molecular weight of O2 as 32 g/mol)

A saturated solution of NaCl contains 6.60 g salt in 20 mL water at 24 C. Calculate the solubility of NaCl in g solute/100g h20 (consider water density as 1 g/mL.)
