Question 49 Which of the following statements is true? O NANO3 increases the solubility of AgBr in water by common-ion effect O Addition of NaBr will increase the solubility of AgBr in water. O lonic strength is a quantity that only depends on the concentration of the ions in a solution. O lons common to the salt being dissolved in water causes shielding effect which increases its solubility. O Solubility of AgCl is higher in an aqueous solution with higher ionic strength. 2p Question 50
