Explanation:
A compound is a substance that consists of atoms of two or more various elements such that the atoms are chemically joined together.
For example, water is a compound made up of hydrogen and oxygen.
A material being examined is the same throughout such that the material contains carbon and oxygen that are chemically combined. This material is compound.
A substance with a Ka of 1 x 10^-5 mol dm^-3 has a pKa of:
pKa = -logKa = 5
This is a relatively large pKa for an acid, so it is not very acidic, classifying it as a weak acid.
Hope this helps!
