Concentration

The video explains the concept of solutions, using examples like salt in water and oxygen in the atmosphere. It defines concentrated solutions as those with a high proportion of solute. The video also distinguishes between concentrated and dilute acids, highlighting that concentrated acids have little to no solvent mixed in.

What is an example of a solution where a gas is dispersed in another substance?

• Salt in water

• Oil in water

• Sugar in tea

• Oxygen in the atmosphere

What characterizes a concentrated solution?

• No solute present

• High proportion of solute

• Low proportion of solute

• Equal proportion of solute and solvent

Which of the following is NOT a characteristic of a concentrated solution?

• Low solute concentration

• More solute than solvent

• High solute concentration

• Dense solution

How does a concentrated acid differ from a dilute acid?

• It has less or no solvent mixed in

• It is more diluted

• It is less reactive

• It has more water mixed in

In the context of acids, what does 'dilute' mean?

• No solvent present

• Mixed with a small amount of solvent

• Mixed with a large amount of solvent

• Highly reactive
