Acids, Bases and Salts — Class 10 CBSE Science revision notes
A 6-page visual revision sheet for Acids, Bases and Salts, written for Class 10 CBSE Science. Formulas, diagrams and the traps that cost marks, laid out to be read the night before rather than the term before. Free, and it opens inside CapCompass.
What this Acids, Bases and Salts sheet covers
- Acid
- Base
- Salt and water
- Indicators
- Chemical properties of acids and bases
- Properties of acids and bases
- What the indicators say
- Litmus
- Methyl orange
- Phenolphthalein
- Olfactory kinds
- Strong and weak, concentrated and dilute
- Strong or weak
- Concentrated or dilute
- Reaction of acids with metals
- Metal carbonate
- Reactions of acids
- acid + metal gives salt + hydrogen
- acid + metal carbonate gives salt + water + carbon dioxide
- acid + metal hydrogencarbonate, the same three products
- acid + metal oxide gives salt + water, a basic oxide neutralised
- acid + base gives salt + water
- Reactions of bases
- base + non-metal oxide gives salt + water, an acidic oxide neutralised
- base + metal, only some metals, and the gas is hydrogen again
- the limewater test, and the milkiness is the precipitate
- excess carbon dioxide dissolves the milkiness away again
- Testing the gas that came off
- Neutralisation is an ion cancelling out
- pH scale
- Strength of acid or base
- The pH scale
- pH as a power of ten
- Importance of pH in everyday life
- pH in everyday life
- Family of salts
- pH of salts
- Salts and their family
- Chlor-alkali process
- Bleaching powder
- Baking soda
- Washing soda
- Common salt and the chemicals made from it
- electrolysis of brine, the chlor-alkali process
- bleaching powder, from chlorine and dry slaked lime
- baking soda, sodium hydrogencarbonate
- heating baking soda, which is what makes a cake rise
- washing soda, by recrystallising sodium carbonate
- Salts and their uses
- What each one is used for
- Plaster of Paris
- Water of crystallisation
- Traps that cost marks
- Tricks that save time
How CapCompass uses this sheet
These notes are not a standalone PDF. CapCompass plans Science chapter by chapter against your real exam dates and free hours, and when the plan reaches Acids, Bases and Salts the sheet opens inside the study block itself — at the page covering the sub-topic that block is on, with the timer still running. Revision arrives at the moment the plan says revise, instead of having to be gone looking for.
