if the surface area of a solid solute is increased, what effect will this have on the rate of dissolution in an aqueous solution?

It will increase the rate of dissolution.

It will decrease the rate of dissolution

It will have no effect on the rate of dissolution

It will cause the solute to remain on dissolved.

Which of the following factors would NOT affect the rate of dissolution of solid solutes in an aqueous solution?

Amount of surface area of the solvent

Which of the following is true of agitation and its effect on the rate of dissolution of solid solutes in aqueous Solutions?

Agitation increases the rate of dissolution by increasing the surface area of the solute

Agitation has no effect on the rate of dissolution

Agitation decreases the rate of dissolution by reducing the solubility of the solute

Agitation decreases the rate of dissolution by decreasing the surface area of a solute

What is a solvent in an aqueous solution?

The substance that dissolves the solute

The substance that is dissolved in the solution

The substance that remains unchanged

The substance that reacts with the solute to form a new compound

What is the rate of dissolving?

How fast a solute dissolves in a solvent

The amount of solute that can dissolve in a solvent

The size of the solute particles

The temperature at which a solute dissolves

Which answer choice correctly identifies the solute and solvent in the example?

Water is the solvent, and sugar is the solute

Water is the solute, and sugar is the solvent

Water and sugar are both solutes, the finished solution is the solvent

Water and sugar are both solutes, the finished solution is the solvent.

2 g of salt is placed into a glass of cold water and also into a glass of warm water. Which glass will have the fastest rate of dissolution?

The rates of dissolving will be equal

Coarse table salt and fine table salt are both put into a beaker of warm water. Which salt will dissolve first?

The fine table salt will dissolve first

The coarse sea salt will dissolve first

They will dissolve at the same rate

Salt does not dissolve in water.

The process of solutes dissolving into a solvent.

The process of combining solvents and solutes.

The separation of solutes from a solvent.

What does the Rate of Dissolution measure?

How quickly a solute dissolves in a solvent.

The amount of solute in a solution.

The time it takes for a solution to evaporate.

Name three factors that influence the rate of dissolution.

Temperature, surface area, and agitation.

Temperature, pressure, and color.

Why does warm tea dissolve more sugar than cold tea?

Warm tea has more energy, breaking sugar bonds faster, and can hold more dissolved sugar.

Cold tea can hold more dissolved sugar.

Stirring or mixing, increasing solute-solvent collisions.

The separation of solute from solvent.

The process of combining solvents and solutes.

How does stirring impact the rate of dissolution?

Stirring speeds up dissolution by breaking solute particles and spreading them.

It has no effect on dissolution.

How does the dissolution process change when the rate of dissolution is increased?

An increased rate means a faster and more efficient mixing, resulting in a homogeneous solution.

The concentration of a mixture can be increased in which of the following ways?

Increasing the amount of solute

Increasing the amount of solvent

What does it mean to dilute a solution?

reduce the amount of solute per solvent

increase the amount of solute per solvent

increase the temperature of the solvent

increase the temperature of the solute

Solids dissolve faster at higher temperatures because

the molecules of the solvent have more energy and move quickly.

the molecules of the solvent have less energy and move slower.

the particles of solvents at higher temperatures are densely packed and only vibrate in place.
