6. Increasing the surface area of a solid __ a. slows the speed of dissolving c. increases the speed of dissolving b. has no effect on the speed of dissolving d. causes the solid to ionize

c. increases the speed of dissolving<br /><br />Increasing the surface area of a solid increases the speed of dissolving. This is because a larger surface area allows more particles of the solid to come into contact with the solvent, leading to a faster dissolution rate.
