well, you haven't mentioned the name of any chemical but i'm randomly going to select some chemicals and their pH values as follows:
Name of chemical - pH value
Hydrochloric acid - 1 to 2
Water(pure) - 7
NaOH - 10 to 11
methyl orange - 3.2 to 4.5
phenolphtalein -8.2 to 10.0
bromothymol blue -6 to 7
ethanoic acid -4.5 to 5.5

pH of acids varies from 1-7, pH of bases varies from 8-14 and 7 is neutral i.e. it is neither acidic nor basic.
