Questions & Step-by-Step Solutions

What is the Ksp expression for the salt Ag2SO4?
  • Step 1: Write the formula of the salt, which is Ag2SO4.
  • Step 2: Understand that when Ag2SO4 dissolves in water, it breaks down into its ions.
  • Step 3: Write the dissociation equation: Ag2SO4 ⇌ 2Ag+ + SO4^2-.
  • Step 4: Identify the ions produced: 2 silver ions (Ag+) and 1 sulfate ion (SO4^2-).
  • Step 5: Write the Ksp expression using the concentrations of the ions: Ksp = [Ag+]^2[SO4^2-].
  • Step 6: Remember that the coefficient in front of each ion in the dissociation equation becomes the exponent in the Ksp expression.
