40. Solving a chemistry problem

1. The properties that characterize IUD solutions as true solutions include:
a) lyophilicity;
b) light scattering;
c) numbness
2. What is the charge of the protein Pt-COO-NH3 (IET 10) in a solution of hydrochloric acid with a concentration of 0.2 mol/l
a) positive
b) negative
c) has no charge

3. On one side of the membrane, a solution of RCl protein with a concentration of 0.1 mol/l is placed, on the other side, a solution of sodium chloride with a concentration of 0.2 mol/l. The concentration of chloride ions on both sides of the membrane - when equilibrium is established, will be equal to:
a) CH=0.18; St=0.12
b) CH=0.12; St=0.18
c) CH=0.15; St=0.15

5. The destruction of lyophilic colloidal solutions as a result of complete desolvation of micelles, accompanied by the release of IUDs in the form of flakes, is called:
a) solubilization;
b) salting out;
c) coagulation.
