Acid–Base Titrations (OCR A-Level Chemistry A): Flashcards

Precise analytical technique measuring complete reaction volumes

Precisely known concentration

Bottom of meniscus exactly on graduation mark

Mix solution thoroughly for uniform concentration

Nearest $0.05 ext{ cm}^3$, always two decimal places

Volume of solution added from burette

Two titres agreeing within $0.10 ext{ cm}^3$

$n = c \times \frac{V}{1000}$

1. Find moles known 2. Use equation 3. Calc unknown

Erroneously large titre value
