LATTEST UPDATE 2025/2026 GRADED A+
Silver nitrate+ nitric acid + chloride ions
White precipitate
Silver nitrate+ nitric acid + bromide ions
Cream precipitate
Silver nitrate+ nitric acid + iodide ions
Yellow precipitate
Substances that decolorise bromine water
Alkenes
Electrophiles
Electron pair acceptors, attracted to electrons e.g H+
, NaF and NaCl
Produces misty fumes with conc sulphuric acid
NaBr
Produces misty and orange/brown fumes with conc sulphuric acid
NaI
Produces misty fumes, purple vapour, bad egg smell with conc sulphuric acid
Le chateliers principle
If a factor affecting the equilibrium is changed the equilibrium will shift to oppose this change
Enthalpy change
The overall temperature change at a constant pressure of a reaction
Hess's law
The overall enthalpy change of a reaction at a constant pressure is independent to the route taken
Why does E-Z isomerism occur
