Solutions & Solubility
This part of a solution is what gets dissolved.
What is the solute?
This process increases the contact between solute and solvent by movement.
What is agitation (stirring)?
A pH of 7 is considered this.
What is neutral?
Concentration is the amount of solute divided by this.
What is the amount of solution?
Vinegar has a pH of about 2–3. It is a(n):
What is acid?
This is the substance doing the dissolving, usually in greater quantity.
What is the solvent?
What effect does increased surface area have on the rate of dissolution?
What is increases it?

What is blue?
The unit used to measure concentration.
What is molarity (mol/L)?
Lemon juice is an example of this type of substance.
What is an acid?
A solution forms when this process occurs.
What is dissolving?

What is stronger?
This cleaning-related liquid has a pH of 9–10.
What is soapy water?
True or False: Surface area changes the solubility of a solute.
What is false?
This does not change the solubility limit but speeds up dissolving.
What is stirring or surface area?
