I dissolved EDTA (2 g per liter) in half amount of water and then dissolved CMC (10 g per liter) in it using a stirr (8 h). Solution was left in 4 *C. For next day i added rest of water and mixed , but without stirring. Solution was a bit to viscosus.
What do you thithk, ? after solution of CMC should I heat the solution and than add water and use stirr to get proper solution of CMC ? or use less amout of CMC?

Hi Monika Sitarek-Andrzejczyk
What type of CMC are you using? For there are high viscosity and low viscosity. The low viscosity is the best because it is easier to dissolve and does not become sticky even if you stay in the refrigerator for days. If using high viscosity the solution will become sticky. You can heat it up before using it, you just can't let it boil.
The concentration is good, if you want to save on reagent, you can use half or even less.
