Ksp Expressions and ICE Tables

This video tutorial reviews shortcuts for determining equilibrium equations using ICE tables. It covers examples of salts dissociating in different ratios, such as silver bromide, lead(II) chloride, and calcium phosphate, and explains how to set up Ksp expressions. The video concludes with a summary of the examples and a preview of the next video, which will cover more complex salt dissociations.

What is the Ksp expression for a salt that dissociates in a one-to-one ratio?

• 27x to the fourth

• x squared

• 4x cubed

• 108x to the fifth

In the context of ICE tables, what does the 'x' represent for lead(II) chloride at equilibrium?

• The equilibrium concentration of lead ions

• The change in concentration of lead ions

• The initial concentration of lead(II) chloride

• The initial concentration of chloride ions

How does the Ksp expression change for a salt that dissociates in a one-to-two ratio?

• It becomes 27x to the fourth

• It becomes x squared

• It becomes 4x cubed

• It becomes 108x to the fifth

What is the Ksp expression for calcium phosphate?

• 27x to the fourth

• 4x cubed

• x squared

• 108x to the fifth

Which coefficient is used twice in the Ksp expression for calcium phosphate?

• The coefficient of water

• The coefficient of calcium

• The coefficient of lead

• The coefficient of phosphate

What is the significance of the coefficient in the Ksp expression?

• It is used as both the coefficient of x and the exponent

• It is only used in the initial row of the ICE table

• It determines the initial concentration

• It has no significance

What is the Ksp expression for a salt with a one-to-four dissociation ratio?

• 256x to the fifth

• 108x to the fifth

• 4x cubed

• x squared

What is the Ksp expression for iron(III) hydroxide?

• 108x to the fifth

• 4x cubed

• 27x to the fourth

• x squared

Why is it not necessary to set up a full ICE table for showing work?

• Because the change in concentration is negligible

• Because the initial concentrations are always zero

• Because the equilibrium row is sufficient

• Because the Ksp expression is always the same

What will the next video focus on?

• Salts with one-to-one dissociation ratios

• Salts with non-one-to-one dissociation ratios

• The history of equilibrium equations

• The importance of ICE tables
