• All hydroxides are soluble in water

What is the effect of surface area on the rate of dissolution?

• Increasing surface area has no effect

• Increasing surface area decreases the rate

• Increasing surface area increases the rate

• Increasing surface area first increases the rate, then decreases it

Which of the following statements about the rate of dissolution is TRUE?
