Apparatus that delivers a variable, accurately measured volume of solution?
- Pipette
- Measuring cylinder
- Beaker
- BuretteRight answer
What this set covers
The apparatus, indicators and calculations of an acid-alkali titration. It covers burette, pipette and volumetric flask, phenolphthalein and methyl orange, end point, concordant titres, reading the meniscus, and moles and concentration from the titre.
- Common mix-up
- Students often forget the mole ratio: with H₂SO₄ + 2NaOH, the moles of NaOH are double the moles of acid, so skipping the ratio gives the wrong concentration.
- Review tip
- Take one titration result and write out the calculation in four lines: moles of the known solution, the ratio, moles of the unknown, then concentration.

Play it as a class game
Play this set opens it in splycr, where you can host it for your class straight away. Hosting needs no account: put the room code on the projector, and students join from a phone with the code and their first name. Each question plays as multiple choice, and the three wrong options were written for that question.
