Soluble salts: Salt solutions can be crystallised to produce solid salts.

AQA·GCSE

8464

Soluble salts: Soluble salts can be made from acids by reacting them with solid insoluble substances, such as metals, metal oxides, hydroxides or carbonates. The solid is added to the acid until no more reacts and the excess solid is filtered off to produce a solution of the salt.

Solve equations approximately using simple iterative methods; be able to draw associated cobweb and staircase diagrams

Pearson Edexcel·A-Level

9MA0

Simple iterative methods turn difficult root equations into a repeatable numerical routine: feed each answer back into \(x_{n+1}=g(x_n)\). For Pearson Edexcel 9.2, marks come from accurate iteration, a correctly constructed cobweb or staircase diagram, and a precise conclusion about convergence at the fixed point.

Solve equations using the Newton-Raphson method and other recurrence relations of the form xₙ₊₁ = g(xₙ); understand how such methods can fail

Pearson Edexcel·A-Level

9MA0

Newton-Raphson and recurrence relations let you approximate roots that algebra cannot conveniently solve. For Pearson Edexcel, the highest marks come from pairing accurate calculator work with a clear function, derivative or recurrence, and a geometric explanation of convergence or failure.
