Solutions: Solute & Solvent

By: JINKY N. ORAIZ

Let’s Recall:What is a

SOLUTION?

Solutions are homogeneous

mixtures of two or more substances

(that means, they are uniform all throughout)

Let’s Recall:What is a

SOLUTION?

Solutions Have a single

phase system (that means, it is

uniform in it’s phase throughout)

Let’s Recall:What is a

SOLUTION?

Solutions consist of a solvent

and one or more solutes

5

Solutions: Solute and Solvent

A solution is composed of a solvent and one or more solutes

6

Solutions: Solute and Solvent

Solvent = WATERSolute = SALT

7

Solutions: Solute and Solvent

Solvent = WATERSolute = White Sugar

White Sugar and Water

8

Natural or Manufactured? Natural Solutions

Air – oxygen and other gasses dissolved in nitrogenRain – oxygen and CO2 dissolved in waterSea Water – salt and other mineral dissolved in water

Manufactured or Processed

Vinegar – 5% acetic acid mixed in waterGasoline – mixture of different hydrocarbonsMetal Alloy –

steel = brass and tinbrass = copper and zinc
