Numéro d’image : 11519481
| Dissolving potassium permanganate (Second of 3 images). Potassium permanganate dissolving in a test tube of water. The potassium permanganate was added about 30 minutes ago and is beginning to dissolve. Dissolving occurs because there is electrostatic attraction between the water molecules and those of the solid. The water pulls ions away from the surface of the solid and into the fluid. In this way the potassium permanganate (the solute) slowly dissolves into the water (the solvent) to form a homogeneous mixture (solution,purple). The amount of solute that water can hold in solution depends upon its temperature and pressure. (See also A350/110 and A350/112) | |
