If `200ml` of `0.2 M BaCl_(2)` solution is mixed with `500ml` of `0.1M Na_(2)SO_(4)` solution. Calculate osmotic pressure of resulting solutions?

Text Solution

Verified by Experts

`BaCl_(2)+Na_(2)SO_(4)rarrBaSO_(4)+2NaCl`
`{:(0.04"moles",0.05,0,0),(0,0.01,"No effect",0.08),(,(0.01)/(0.7),"No effect",(0.08)/(0.7)):}`
`pi=(i_(1)C_(1)+i_(2)C_(2))RT`.
`=(3xx(0.01)/(0.7)+2xx(0.08)/(0.7))0.082xx300.=6.685` atm.
