Rate of dissolving

Front

What is the rate of dissolution?

Back

The rate of dissolution refers to how quickly a solute dissolves in a solvent, influenced by factors such as temperature, surface area, and agitation.

Front

Which factor does NOT increase the rate of dissolution for solids?

Back

Decreasing the temperature.

Front

How does the size of solute particles affect the rate of dissolution?

Back

Smaller solute particles have a larger surface area, which increases the rate of dissolution.

Front

What is the term for the substance that is dissolved in a solution?

Back

Solute.

Front

What happens to the rate of dissolution when the temperature of the solvent is increased?

Back

The rate of dissolution generally increases with higher temperatures.

Front

If you have equal masses of crushed table salt and a cube of table salt, which will dissolve faster?

Back

Crushed table salt will dissolve faster due to its increased surface area.

Front

What is the effect of stirring on the rate of dissolution?

Back

Stirring increases the rate of dissolution by distributing the solute particles throughout the solvent more quickly.

Front

Why do smaller salt crystals dissolve faster than larger ones?

Back

Smaller salt crystals have a greater surface area exposed to the solvent, allowing for more interactions and faster dissolution.

Front

What is the relationship between surface area and the rate of dissolution?

Back

An increase in surface area leads to an increase in the rate of dissolution.

Front

What is the role of temperature in the dissolution process?

Back

Temperature affects the kinetic energy of molecules; higher temperatures increase molecular movement, leading to faster dissolution.
