What is another term for a solution, based on its composition?
Another term for a solution is a homogeneous mixture.
Can solutions exist in states other than liquid?
Yes, solutions are homogeneous mixtures and can exist as solids, liquids, or gases.
What is a solution?
A solution is a homogeneous mixture with uniform macroscopic properties that can exist as a solid, liquid, or gas.
What does it mean for a solution to have 'uniform macroscopic properties'?
It means that any sample taken from the solution will have the same composition and appearance, regardless of where it was taken from.
What is a key characteristic of a heterogeneous mixture?
A key characteristic of a heterogeneous mixture is that its properties are not uniform and vary depending on the location within the mixture.
Define Molarity (M).
Molarity is the most common way to express solution composition, defined as the moles of solute per liter of solution.
How do the properties of a homogeneous mixture differ from those of a heterogeneous mixture?
Homogeneous mixtures (solutions) have uniform macroscopic properties throughout, while heterogeneous mixtures have properties that vary with location.
What is the formula for calculating molarity?
The formula for molarity is M = moles_solute / L_solution.
If you know the molarity and volume of a solution, what quantity of the solute can you calculate?
You can calculate the number of moles of solute particles by rearranging the molarity formula (moles_solute = M x L_solution).
How would you calculate the volume of a solution if you know its molarity and the moles of solute?
You would calculate the volume by dividing the moles of solute by the molarity of the solution (L_solution = moles_solute / M).
