Morning folks,

I have been asked to make up Red & Blue Litmus, I can only guess, I need to add acid for the colour change???? Why would this be needed??


Regards

Cant you buy Red and Blue Litmus Paper. I must admit that most of my papers have turned red in the chem store.

Does the teacher want Red and Blue Litmus Solution or Paper?

or am i asking a very stupid question?

Hi Sam, No you are not asking a silly question. They did ask for Blue & Red Liquid solution Litmus.

Regards
