I think I have written stupid things
1a) I wrote: "Magnesium ions make the bath water hard but the Magnesium ends up in a precipitate with the carbonate which won't react making the water soft?
1c) I wrote: "Water can't stay at 100C meaning it wouldn't be easy to obtain a good result and water evaporates at 100C"
1d) I wrote: "She was surprised as it rose then fall which is against the typical trend of solubility increasing as temperature increases" ?
3b) I put: "They all have 2 outer shell electrons and a lower energy level which isn't full and the 2 outer shell electrons are lost to form 2+ ions giving similar chemical properties"
4b) I put: "Stronger acid has lower pH as there are more H+ ions and it is fully ionised compared to weaker acid."
5bii) I put: "Sensitivity means smaller amounts can be detected increasing precision"
How many of those do you think are right.. I seem to have not put my ideas down too clearly
