# What is Q in KSP?

Contents

The reaction quotient, Q, can be used to determine whether a precipitate will form with a given concentration of ions. … If Q < Ksp, no precipitate will form. If Q = Ksp, a precipitate will form. If Q > Ksp, a precipitate will form.

## How do you calculate Q?

We can calculate Q by writing out the equation using the balanced reaction and then using the given concentrations. If we compare Q to K, we can see that Q > K Q > K Q>KQ, is greater than, K.

## What is the formula for KSP?

Calculate the value of Ksp . Using mole ratios, the [Ag+] will go up by (2 x 1.31 x 10-4 moles/L) = 2.62 x 10-4 moles/L.

## What will happen to a solution where Q KSP?

If more solid as added to an unsaturated solution, it dissolves until the solution is saturated (at which point there is solid in equilibrium with the solvated ions). … If Q < Ksp, the solution is unsaturated and no precipitation will occur.

## What is Q in Nernst equation?

The Equation above indicates that the electrical potential of a cell depends upon the reaction quotient Q of the reaction. As the redox reaction proceeds, reactants are consumed, and thus concentration of reactants decreases. Conversely, the products concentration increases due to the increased in products formation.

## What is Q equal to?

Q can be used to determine which direction a reaction will shift to reach equilibrium. If K > Q, a reaction will proceed forward, converting reactants into products. If K < Q, the reaction will proceed in the reverse direction, converting products into reactants. If Q = K then the system is already at equilibrium.

## What if Q is less than KSP?

The reaction quotient, Q, can be used to determine whether a precipitate will form with a given concentration of ions. … If Q < Ksp, no precipitate will form. If Q = Ksp, a precipitate will form. If Q > Ksp, a precipitate will form.

## What is a high Ksp?

Ksp (Solubility product constant) is the equilibrium between a solid and its respective ions in a solution. … For example the higher the Ksp the more soluble the compound is.

## Which KSP will precipitate first?

When two anions form slightly soluble compounds with the same cation, or when two cations form slightly soluble compounds with the same anion, the less soluble compound (usually, the compound with the smaller Ksp) generally precipitates first when we add a precipitating agent to a solution containing both anions (or …

## How does temperature affect KSP?

Temperature. Most solutes become more soluble in a liquid as the temperature is increased. … Temperature affects the solubility of both solids and gases but hasn’t been found to have a defined impact on the solubility of liquids.
