Titration calculation one was 0.21mol/dm^3
one about sodium iodide or something it was yellow precipitate
6 marker was on calorimtery thingy measuring energy change so what i said was like record initial temp, mass of water, alcohol burner, then you light burner leave for 5 mins come back and blow it out and measure final temp, mass of what, alcohol burner and then u can calculate energy change
5 marker on titration
Measure acid use pipette to squeeze into flask
Put white tile under flask
add few drops of indicator in flask
Use pipette & squeeze the sodium hydroxide or w/e it was into burette and keep adding it until colour change/end point is reached
last question was bond making & bond breaking thingy
question about ticking boxes of energy change graphs etcc
question about rate of reaction calculation is 0.6
question on alumnium and idenitfying magnesium using excess sodium hydroxide
magnesium is present if solution dissolves in exccess sodium hydroxide
question about halide ions where everything was no change except for iron (II)) thingy which was green precipitate
