lowering of solubility of the first solution when an another solution is added having the same ions is called common ion effect.
What else can I help you with?
What addition to a saturated solution of PbCrO4 leads to the common ion effect?
Adding Pb2+ ions to a saturated solution of PbCrO4 would lead to the common ion effect. The additional Pb2+ ions would increase the concentration of the common ion in the solution, shifting the equilibrium to the left and causing more PbCrO4 to precipitate out of the solution.
How does the common-ion effect influence the Ph?
The common-ion effect decreases the solubility of a slightly soluble salt in a solution that already contains one of the ions of the salt. This leads to a decrease in the pH of the solution due to the shift in the equilibrium of the dissociation reaction towards the production of more undissociated molecules and fewer ions.
What does the Common Ion Effect state?
The Common Ion Effect states that the solubility of a slightly soluble salt is reduced when it is dissolved in a solution that already contains one of the ions in the salt. This occurs because the common ion suppresses the dissociation of the salt, shifting the equilibrium towards the solid state.
What common ions are most often found in acids and bases?
Common ions found in acids include H+ (hydrogen ion) and in bases, common ions include OH- (hydroxide ion) and metal ions like Na+ (sodium ion) and K+ (potassium ion).
Can you provide some common ion effect practice problems for me to work on?
Here are some common ion effect practice problems for you to work on: Calculate the solubility of silver chloride (AgCl) in a solution containing 0.1 M of chloride ions (Cl-) using the common ion effect. Determine the pH of a solution containing 0.2 M of acetic acid (CH3COOH) and 0.1 M of sodium acetate (CH3COONa) using the common ion effect. Predict the effect of adding potassium nitrate (KNO3) to a saturated solution of lead(II) chloride (PbCl2) on the solubility of the salt, considering the common ion effect. These practice problems will help you understand and apply the common ion effect in various scenarios.

Which ions have a positive charge?
Ions with a positive charge are called cations. Common cations include hydrogen ions (H+), sodium ions (Na+), and calcium ions (Ca2+).
What effect does changing the concentration of calcium ions have on the coagulation of milk?
the rate of coagulation increases as the concentration of calcium ions increase.
How NH4 NO2 NO3 effect pH in water?
When ammonium nitrite (NH4NO2) dissolves in water, it forms nitrite (NO2-) ions and ammonium (NH4+) ions, which can be slightly acidic due to the release of hydrogen ions (H+). On the other hand, nitrate (NO3-) ions from ammonium nitrate (NH4NO3) do not have a significant impact on water pH as they are neutral. Overall, the net effect on water pH will depend on the relative amounts and concentrations of these ions present.
What affects the solubility of ions?
The solubility of ions is affected by factors such as the nature of the ion (charge and size), the nature of the solvent, and the common ion effect. Additionally, temperature can influence solubility, with some compounds becoming more soluble at higher temperatures while others may become less soluble.
Which metal was oxidized by two other ions?
Iron (Fe) is a metal that can be oxidized by two common ions: copper ions (Cu^2+) and silver ions (Ag^+).
What was the effect of sodium ions on heart rate?
