Calculations for preparing a K2CO3 solution
Thread Content
Seeking help: The current concentration of the K2CO3 solution in the system is approximately 17%, and the total volume of the equipment and pipelines is about 240 m3; it is necessary to adjust the concentration to around 20%. Now, the manufacturer offers 3 options for preparation: ① K2CO3 powder, ② a 50% K2CO3 solution, and ③ a KOH solution with a mass ratio of 45%. Please advise on how much of each of these 3 options is required
I’m just a middle school student. The second option seems more feasible and easier to implement. Assuming that the total volume is 240 cubic meters, then 20%*240 = 50%*(240-v) + 17%*v; this can be used to calculate the value
