I have a problem keeping litmus indicator, it tends to go off and smelly, what am I doing wrong?, I follow the instructions when making it up and filter it well, does anyone have any suggestions.
Cheers, Lisa

Litmus Solution
Hi Lis
This is my receipe for Litmus Indicator Blue and Red:
Makes 500ml solution:
Boil 10 grams of Litmus granules in 500mls distilled water.
Let cool and then filter.
To make Blue Litmus,Red:
Just add drops of HCl until you achieve the red colour. Label and store in a glass reagent bottle.
There you go, easy ay!!!
Good luck
