Acids, Alkalis And Titrations
Bayani Gaba-gaba
Every liquid you encounter, from lemon juice to bleach, sits somewhere on the pH scale. Knowing whether a substance is acidic, neutral, or alkaline is fundamental to chemistry, medicine, agriculture, and everyday life. Indicators give you a quick visual answer, while the pH scale puts a precise number on it.
In this lesson you will learn how to use litmus, phenolphthalein, and methyl orange to distinguish acids from alkalis, understand the pH scale from 0 to 14, use universal indicator to estimate pH, and discover why acids and alkalis behave the way they do at the ionic level. You will also see how neutralisation reactions work and why they always produce water.
Manufura
- Describe the use of litmus, phenolphthalein and methyl orange to distinguish between acidic and alkaline solutions
- Understand how to use the pH scale to classify solutions
- Describe the use of universal indicator to measure the approximate pH value of an aqueous solution
- Know that acids in aqueous solution are a source of hydrogen ions and alkalis are a source of hydroxide ions
- Know that alkalis can neutralise acids
