Question

Find the concentration of sodium chloride required to make a 5% solution of procaine HCl iso osmotic with blood plasma. The

freezing point of 1%w/v solution of procaine HCl is 0.1220

c and that of sodium chloride is 0.5760

c.​

Answer 1

Answer:

Explanation:

The easiest way to calculate the osmotic pressure of a solution is to utilise the more ... which must have a freezing point depression of 0.52◦C for them to be isotonic with blood plasma ... of 1% w/v sodium chloride solution is 0.576. ... prepare 150ml of a 2% w/v solution of lidocaine hydrochloride isotonic with blood plasma?
