Today in class we got our mid-term results back. Afterwards we learnt about CONCENTRATION

WHAT IS A SOLUTION?

a solution is a homogeneous mixture.--> not being able to differ the different substances mixed

WHAT IS A SOLVENT?

component presented in larger component

WHAT IS SOLUTE?

the component present in the SMALLER amount.

for example: SALT in WATER. water= SOLVENT salt= SOLUTE :)

WHAT IS CONCENTRATION?

the amount of solute over the amount of solvent
