How could you determine the concentration of a specific molecule, ion or active ingredient in a household item?
Household items
-
acetone
Active ingredients: propylene (C3H6), benzene (C6H6)
Dish soap
Active ingredients: triclosan (C12H7Cl3O2) 0.3%, chloroxylenol (C₈H₉ClO) 3g/1000ml
-
As the active ingredient in dish soap is an organic material titration method won't work to determine the concentration as it's neither an acid or a base
-
Panadol
Active ingredients: Paracetamol (C8H9NO2), 500mg

Key terms
molecule
A molecule is defined as a two or more atoms chemically bonded for example water is a molecule as it is made of three atoms which are chemically bonded
Ion
an atom or multiple atoms which have an electric charge due to having lost or gained an electron due to electronegativity
Active ingredient
An active ingredient is classified as an ingredient that directly has a biological effect on whatever it's targeting, for example in Panadol paracetamol which is the active ingredient that reduces temperature and acts as a painkiller.
Household items
In this problem a household item refers to products stored within most households, for example cleaning products like dish soap and laundry detergent
What is concentration

How to measure
- Identify mass of the solute
- Identify the total mass of the solution
- Divide the mass of the solute by the total mass of the solution
