Question

What pressure would need to be applied to produce pure water from a 0.050M solution of potassium phosphate (K3PO4) by reverse osmosis?

science chemistry

Answer 1

Answer #1

for K3PO4 , i = 4

C = 0.050 M

T = 298 K

pressure = i x C x R x T

= 4 x 0.050 x 0.0821 x 298

= 4.89 atm

pressure needed = 4.89 atm
