Well, substances are generally in Chemistry. It is necessary to classify a substance due to the initial fact that the chemical name could have two meanings; one may have a capital letter and the other may not
A substance with a negative pH value indicates a strong acid with high concentration of hydrogen ions (H+). The lower the pH value, the higher the acidity of the substance. Negative pH values are possible for highly concentrated acids, like hydrochloric acid.
Oxygen is necessary for a substance to burn. It reacts with the substance in a chemical reaction known as combustion, releasing heat and light energy. Without oxygen, the substance will not be able to sustain a fire.
