What exam questions actually test

Titration is several skills, not one calculation

A routine concentration question may only need n = cV and a reacting ratio. Exam questions often add another decision: which titres are concordant, whether a 25.0 cm³ portion represents a larger solution, how a practical mistake changes the result, or how an unfamiliar redox ratio should be used.

This hub keeps those skills visible. That makes it easier to practise the weak step instead of repeatedly doing whole titrations and hoping the problem disappears.

Exam habits

Three things worth getting automatic

Use only suitable titres

Do not automatically average every non-rough result. Decide which values are concordant first.

Track the portion used

A 25.0 cm³ pipetted portion may represent one tenth of a 250.0 cm³ prepared solution. Keep that scaling explicit.

Explain the direction of an error

For apparatus questions, identify what changes physically, then follow that change through to the titre or calculated value.
