This question is probably really basic, and frankly Im a bit embarassed that I am unsure about it.
Well here goes. I need to make a 0,5M Tris-HCl buffer with pH 8 (@ 25 C) in the lab.
I am using Trizma base and Trizma HCl.
Now, I found a chart telling me the required weight of both to make a 0,05M solution.
Trizma base: 2,65 g/L
Trizma HCl: 4,44 g/L
Since I need to make a buffer with a concentration of 0,5M and not 0,05 as the chart tells me, should I just multiply the weight by 10?
Thanks for any advice. I really suck at making buffers and I have to make a lot of them!
