Hi,

i have a quite silly question. I wanted to make 0.5% SDS solutions, using SDS powder. But don't know how to make it. Can anybody help me?

[Prep!]

add 0.5gm SDS to some 70 ml water. disolve and make up teh volume to 100 ml!!!  
precausions to be taken.. don shake too much.. frothing will lead to wrong volume adjustment.. and if the SDS does not dissolve it will do so very easily at 65 degrees in a water bath!!!
Best luck!!!
And ya the question was uite silly!!!

And wear a mask when you weigh the powder
