What is the formula that links moles concentration and volume
Moles = concentration (mol/dm³) x volume (dm³)
How does dm³ link to cm³
1dm³ = 1000 cm³
How to carry out calculations involving gas volumes and the molar volumes of gas at room temperature and pressure.
Volume = moles x 24 dm³
Describe how to carry out an acid - alkali titration
Measure out 25cm³ of HCl using a glass pipette
Transfer to a conical flask
Fill the burette with sodium hydroxide
Take the initial reading on the burette - record to 2dp
Add a few drops of phenolphthalein indicator to the HCl (colourless)
Add sodium hydroxide until indicator changes colour
Take final reading on burette when it reaches the permanent pink colour
What is a titration for
Used to find out precisely how much acid neutralises a certain volume of alkali or vice versa
