On a typical pH test, acids will be yellow-red, a neutral solution will be green and basic solutions will be darker shades of green.
Strong acids include HCl and HBr. Weak acids include HF and HC2H3O2. Also, lemon juice is a weak acid. A neutral solution has equal hydroxide and hydronium concentrations, so it could be a mixture of a strong and weak acid, or water. Basic solutions are soaps. A strong basic solution would be NaOH, CaOH2, etc. Drain de-clogger is an example.
I suggest you pay attention in class, or read in your book, next time. Paying attention to chemistry is extremely important.
