Explanation:
Factory wastes are usually acidic and they pose serious environmental challenges.
If an untreated acidic waste is discharged into the river, the acidity of the river increases and this is toxic to life in the water.
On land, the acid can enter into the soil and prevent plant growth.
Acid discharge can enter the groundwater system and render it unfit for use.
Bases and a couple of additives are used to remove acidity from factory wastes before they are discharged.

There are four types of chemical bonds essential for life to exist: Ionic Bonds, Covalent Bonds, Hydrogen Bonds, and van der Waals interactions. We need all of these different kinds of bonds to play various roles in biochemical interactions. These bonds vary in their strengths.
To play a variety of roles in biochemical interactions, we require all of these diverse sorts of linkages. The tensile strength of these linkages varies. In chemistry, we consider the range of strengths between ionic and covalent bonds to be overlapping. This indicates that in water, ionic bonds usually dissociate. As a result, we shall consider these bonds from strongest to weakest in the following order:
Covalent is followed by ionic, hydrogen, and van der Waals.

1) list givens and convert if necessary
C₁ = 3.50 mol/L
V₁ = 0.550 L
C₂ = ?
V₂ = 0.275 L
2) rearrange formula
3) solve
C₂ = 7.00 mol/L
