Ph scale for acids and alkalis
WebOct 10, 2024 · The pH scale is used to measure acidity and alkalinity. Indicators are substances that change colour with a change in acidity/alkalinity. Litmus is a common indicator; alkaline solutions turn red litmus blue and acid solutions turn blue litmus red. Acids can react with some metals to form a salt and hydrogen gas. Ideas for the classroom WebJul 31, 2024 · A substance is acidic if it has a pH level of 0 through 7, where 0 is the most acidic. A substance is basic, then, if it has a pH level of 7 through 14, where 14 is the most basic. If a substance has a pH of exactly 7, it’s neutral. This means it has equal amounts of hydrogen and hydroxide ions. Pure water is a neutral substance.
