Which one is correct?
Both method can?

I always do 2nd one

Graph

Graph 2 wrong actually...
The end bend down?? When we draw, end point must be highest point...

@shenay.

Thank u very much

then another question.
for ogive,first one always upper boundry then upper upper..rite?

for histogram,first one always lower boundry then upper upper??

lol,small confusion
*
As long all u use upper boundary and the 1st 1 u use lower boundary

The heck continuous variation is in chemistry.

Perhaps rate of reaction / ion identification?
*
Rate of reaction we aim in paper 3..

In salt there is an experiment 7 experiment..
Use 2 soluble salt mix them together..
For example lead(II) nitrate and pottasium chromate(IV)..Both are same molarity...
All the 7 test tube is filled with same amount of pottasium chromate(IV)...
After that the 1st test tube add in 1cm of lead(II) nitrate, 2nd 2cm and so on..
Precipitate will formed..At one of the test tube the precipitate will start to be constant, just assume is 5th test tube..
In 5th test tube the both solution is completely reacted...
This experiment is used to construct the balanced ionic equation

Its in Chapter 8 Form 4. Continuous variation is a quantitative analysis for salts
*
It's not qualitative analysis..It is to construct a balanced ionic equation

i screwed up round one of SPM last year. Re-sitting cuz wanted to do Vet Science, then realized kenot do local, must go over-seas.. I'm not interested in going over-seas.

So now, round 2, private candidate, study by myself, looks like going to Flunk.. so what do I do about my missing Slip tat came in the mail??

It's called double decomposition.

Ya the reaction is double decomposition reaction..
But the experiment is called continous variation

From what i noe displacement must add in a more electropositive metal..
Like a zinc metal..It cant be in solution..
