how can I make a 50% citric acid solution?
Assuming a w/v % solution, you would dissolve 50g solid citric acid in 100ml H2O.
Question should technically go in the HWK section though.
No, you should dissolve 50g of citric acid in such an amount of water that final volume is 100 mL. That's not the same. For diluted solutions - like 2 or 4 % w/v difference is small, but in the case of 50% w/v prepared your way you will get solution that will be in reality about 40% w/v.
thanks for reponses
What I posted before would not make any sense when I think about it. (If I was making the solution in the lab I would add solid and then add water to the 100ml mark of vol flask) Thus it is not 100ml that I would be adding to make the solution.
