The solubility of common salt is 36.0 g in 100 g of water at 20° C. If systems, I, II and III contain 40.0,36.0 and 20.0 g of the salt added to 100.0 g of water in each case, the vapour pressures would be in the order

Question

The solubility of common salt is 36.0 g in 100 g of water at 20° C. If systems, I, II and III contain 40.0,36.0 and 20.0 g of the salt added to 100.0 g of water in each case, the vapour pressures would be in the order (A) I < II < III (B) I > II > III (C) I = II > III (D) I = II < III

Tardigrade Admin · Accepted Answer

I is super saturated, II is saturated and III is unsaturated solution. In solution I and II, amount of dissolved substance is same.

Q. The solubility of common salt is $36.0 g$ in $100 g$ of water at $2 0^{\circ} C$ . If systems, I, II and III contain $40.0, 36.0$ and $20.0 g$ of the salt added to $100.0 g$ of water in each case, the vapour pressures would be in the order

$I < II < III$

$I > II > III$

$I = II > III$

$I = II < III$

I is super saturated, II is saturated and III is unsaturated solution. In solution I and II, amount of dissolved substance is same.

Q. The solubility of common salt is 36.0g in 100g of water at 20∘C. If systems, I, II and III contain 40.0,36.0 and 20.0g of the salt added to 100.0g of water in each case, the vapour pressures would be in the order

I<II<III

I>II>III

I=II>III

I=II<III

I is super saturated, II is saturated and III is unsaturated solution. In solution I and II, amount of dissolved substance is same.

$I > II > III$

$I = II > III$

$I = II < III$
