Concentration Remember a solution is made when one substance dissolves into another Solute: the substance that dissolves Solvent: the substances that does the dissolving example: crystal light (solute) dissolving in water (solvent). Concentration: is the amount of solute dissolved in a specific amount of solvent example: 50g of solute dissolved in 100mL of water. This is read as 50g per 100mL of solution.
Concentration When comparing the concentrations of solutions, you need to know the same amount of solute within the same volume of solvent! Get out your calculators!
Concentration Example: Compare which solution is more concentrated; A: 10g salt/50mL of water or B: 3g salt/10mL of water. Concentration = Amount of solute(g) of Solution Amount of Solvent (ml) Step 1: Find concentration for 1 ml Step 2: Compare concentrations per 100ml
Concentration Example: Compare which solution is more concentrated; A: 10g salt/50mL of water or B: 3g salt/10mL of water. Concentration = Amount of solute(g) of Solution Amount of Solvent (ml) Solution A Step 1: Find concentration for 1 ml =𝟎.𝟐𝒈/𝒎𝒍 Step 2: Compare concentrations per 100ml
Concentration Example: Compare which solution is more concentrated; A: 10g salt/50mL of water or B: 3g salt/10mL of water. Concentration = Amount of solute(g) of Solution Amount of Solvent (ml) Solution B Step 1: Find concentration for 1 ml =𝟎.3𝒈/𝒎𝒍 Step 2: Compare concentrations per 100ml
Concentration Example: Compare which solution is more concentrated; A: 10g salt/50mL of water or B: 3g salt/10mL of water. Comparison Solution A: or Solution B: Solution B is more concentrated
Concentration Unsaturated solution: is when more solute can dissolve within the solution Saturated solution: is when a solute can no longer dissolve within the solution Solubility: the maximum amount of solute you can dissolve at that temperature. Eg. Solubility of ice tea 20 g(in 100ml of water) at 22°C Saturation Point: the stage at which no more solute can be dissolved into the solvent
