Which of the following aqueous solutions should demonstrate the most non-ideal behavior? A. 0.1 M NaI B. 0.2 M CuSO4 C. 0.5 M KB
Maslowich

Answer:

D. 2.0 M CuCl2

Explanation:

The ionic strength of a solution shows the concentration of its ions in that given solution of the compound. Dissolved ionic compounds always dissociate into ions. The total amount of ions in solution will definitely affect the properties of the solution. The concept of ionic strength was first introduced by Lewis and Randall in 1921 while describing the activity coefficients of strong electrolytes.

The ionic strength of CuCl2 is 6M as shown:

ionic strength = 0.5*[(+2)^2*2M + (1-)^2*4M] = 6 M

The higher the ionic strength of a solution, the greater its non ideal behavior.

CuCl2 shows the greatest ionic strength hence the greatest non ideal behavior.

How many moles of oxygen are in 8.25g of O?
posledela
8.25 grams of O2 has 0.258 moles of Oxygen. Here's how you figure that out:
Oxygen is one of the 7 diatomic elements, so it is normally O2.
<span>You find it's molar mass (or mass for </span>one mole<span> of it) by adding up two of the masses from the Periodic Table.</span>
