Solutions, Molarity, %, ppm, Solubility & FPD

Front

What is a solution?

Back

A homogeneous mixture of two or more substances, where one substance (the solute) is dissolved in another (the solvent).

Front

Define molarity (M).

Back

Molarity is a measure of concentration, defined as the number of moles of solute per liter of solution (mol/L).

Front

What is solubility?

Back

Solubility is the maximum amount of solute that can dissolve in a given amount of solvent at a specific temperature and pressure.

Front

What is a saturated solution?

Back

A saturated solution is one in which no more solute can dissolve at a given temperature and pressure.

Front

What is an unsaturated solution?

Back

An unsaturated solution is one that can still dissolve more solute at a given temperature and pressure.

Front

What is a supersaturated solution?

Back

A supersaturated solution contains more solute than can normally dissolve at a given temperature and pressure, often achieved by heating the solution.

Front

How do you calculate moles from molarity and volume?

Back

Moles = Molarity (M) × Volume (L).

Front

How do you calculate molarity from moles and volume?

Back

Molarity (M) = Moles of solute / Volume of solution (L).

Front

What is the molarity of a solution with 2 moles of NaCl in 1 L of water?

Back

2 M (2 moles per liter).

Front

If you have 3 moles of solute in 0.5 L of solution, what is the molarity?

Back

6 M (3 moles / 0.5 L = 6 M).
