Science Solution and Concentration Quiz

Dissolving

A physical process that happens when a substance (the solute) becomes evenly distributed throughout another liquid (the solvent)

Solute

The Substance (solid or gas) that is dissolved/mixed evenly with/in a solution

Solvent

The substance (always a liquid) that does the dissolving in a solution

Solution

a mixture created from solute in solvent

Soluble

A substance is soluble if it dissolves in a particular solvent. Ex: table salt is soluble in water — particles separate and spread evenly through the water so the solution looks uniform

Insoluble

A substance is insoluble if it does not dissolve in a given solvent. Insoluble remain as separate particles, flakes, or layer in the solvent (ex: sand in water)

Mixture

A mixture contains two or more substances combined physically (not chemically). Each substance keeps its own properties

Homogeneous mixture

the solute is distributed uniformly and the mixture looks the same throughout (like koolaid in water)

Solution

A homogeneous mixture where the solute is completely dissolved in the liquid solvent, producing a single uniform appearance

Heterogeneous mixture

the different solutes that are not dissolved nor uniformly distributed and can be seen as distinct parts (like glitter and/in water)

Suspension

A heterogeneous mixture in which solid particles do not dissolve and dispersed throughout a liquid but are large enough to eventually settle out over time

Concentration

tells us how much stuff (solute) is mixed into a certain amount of liquid (solvent).

Concentration

is a measured value to how much solute dissolved in a solvent. We use g/100ml to compare all solutions equally (like a standard scale)

Dilute

A solution that contains a relatively small amount of solute compared to the amount of solvent

Concentrated

A solution that contains a relatively large amount of solute compared to the amount to solvent

Formula

Concentration= (grams of solute ÷ volume of solvent) x 100

Unsaturated Solution

a solution where MORE solute can dissolve in the solvent. It contains LESS than the maximum amount of solute.

Saturated Solution

a solution where NO MORE solute can dissolve in the solvent. It contains THE maximum solute and the HIGHEST concentration for this solution volume and type

Precipitate

Solid solute that is undissolved in the saturated solution and sits at the bottom of the test tube/solution.
