Hi All
Has anyone out there come across a prac. using standard soap solution??? I think the experiment is: [*]Testing Chloride in Water Samples.[*]If you have- how is it made up???
Wait for your replies
Ta!!!!

If the teacher can't tell you how to make it up then whatever you do can't be wrong! So just make it up yourself and it will probably be OK. As the teachers have told me in the past, we only teach bucket chemistry. When you do have to be acurate, they will have the instructions, you can bet.

Hi Mother

Are you sure that you want test chlorides.

As far as I know standard soap solution test is used for testing water hardness if this is what you need info can be found on this website

scroll down to 12.13.10 Test for hardness in water with a standard soap solution
and you will find instructions

Many thanks Jazz.
Teacher did get it wrong,she meant water hardness

Found the recipe for making a standard soap solution via the above link but was wondering how others dissolved the soap flakes in the metho. Does it actually need boiling?
