Element, Compound, Mixture: Sodium Chloride (table salt) that is used for cooking

compound

What is solubility?

The ability of a solute to dissolve in a solvent.

The technique used to separate a mixture depends on ________________________ and _____________.

physical properties of the substances present in the mixture and substance(s) to be obtained from the mixture.

_____________is a metal that is liquid in a room temperature. State the common use of the said metal.

Mercury. It is used in the thermometers.

Give the different properties of an element, compound and mixtures.

Element is pure, made up of 1 kind of atom. Compound are made up of different elements that are chemically combined. Mixtures are not chemically combined.

Give the difference between solubility and rate of solubility.

The rate of solubility is the amount of solute that dissolves in a fixed volume of solvent, given a fixed amount of time

The trapped solid particles that remain on the filter paper is called the ___________.

residue

True of False: A suspension is a mixture that dissolves in a solvent.

False. The insoluble substances are suspended in a liquid or gas.

The pure liquid collected from distillation is called the ____________.

distillate

The liquid that passes through the filter is called the ________________.

filtrate

True or False: When a mixture is formed, no chemical reaction occurs. Hence, a chemical reaction can be separated easily by physical methods.

True

Give 3 factors that can affect the solubility of a solute.

nature of the solvent, nature of the solute, temperature

Give 3 factors that can affect the rate of solubility.

temperature, size of solute particles, rate of stirring

_____________________ is the technique used to separate dissolve solids from a solid-liquid mixture.

Evaporation

_________________ is the technique used to separate a pure liquid from a solid-liquid or liquid-liquid mixture.

Distillation

Explain why solid particles can be separated from a liquid by filtration.

The filter paper allows tiny water molecules to pass through the tiny pores in the paper, whilst holding back the much larger particles of solid.

True or False: The elements that make up a compound are always combined in a fixed proportion.

True

A technique used to separate different dyes in the ink mixture.

chromatography

Element, Compound, Mixture: It can be broken down by chemical methods.
