Which factor increases the rate of dissolution?
Which factor increases the rate of dissolution?
Temperature. Heating up the solvent gives the molecules more kinetic energy. The more rapid motion means that the solvent molecules collide with the solute with greater frequency and the collisions occur with more force. Both factors increase the rate at which the solute dissolves.
What happens when you add more solute to an unsaturated solution?
Briefly, most solutes dissolve to a certain extend in a solvent. When you can add more solute which continues to dissolve, your solution is said to be unsaturated. When a solution that has had more solute dissolved at a higher temperature is now cooled, it becomes supersaturated at the lower temperature.
What happens when supersaturated solution is cooled?
What happens when a supersaturated solution is cooled? The solid crystals in the hydrated crystals will dissolve into the bath, forming a supersaturated solution. When the solution for sodium thiosulfate is gradually cooled the super-saturated solution should remain liquid.
Will the solubility of pbco3 increase or decrease as the pH is lowered?
No effect on solubility. Increased solubility. If the pH is decreased, the [H3O+] increases and the [OH-‐] decreases. Thus, the Ksp reaction will shift to the right to replace the decrease in hydroxide ions.
Does adding a strong acid increase solubility?
As more acid is added to a suspension of Mg(OH)2, the equilibrium shown in Equation 16.4. 1 shows how to calculate the solubility effect of adding a strong acid to a solution of a sparingly soluble salt. Sparingly soluble salts derived from weak acids tend to be more soluble in an acidic solution.
Is mgco3 soluble or insoluble?
Explanation: Per the solubility rules, the carbonates of Group 2 metals are insoluble. Thus, MgCO3 is insoluble. Its solubility is only 14 mg/100 mL.
