Which of the following statements is TRUE? A) The solubility of a solid in water

Question

Which of the following statements is TRUE? A) The solubility of a solid in water generally decreases with increasing temperature B) The solubility of a gas in water usually increases with increasing temperature. C) The solubility of a gas in water usually decreases with decreasing pressure. D) The solubility of an ionic solid in water decreases with increasing temperature. E) None of the above statements are true. Which of the following equations represents "Boyle's law"? A) P/V = k B) V/T = k C) VT = K D) PV = K E) V/n = k

Explanation / Answer

1) more is the pressure on gases more is the solubility of gases in water so option (c) is true

2) Boyle's law

"At constant temparature, the pressure given mass of the gas is inversely proportional to it's volume "

P 1/V

P * V = constant (K)

option (D)
