Answer Details
Sodium aluminate (III) is important in water treatment because it causes coagulation. Coagulation is the process of removing suspended particles from water by causing them to stick together and form larger particles that can be easily removed. Sodium aluminate (III) is added to water to create positively charged particles, which attract and bind with negatively charged particles in the water. This causes the suspended particles to clump together and settle at the bottom, making it easier to remove them from the water. Therefore, sodium aluminate (III) helps to improve the quality of water by making it cleaner and safer to use.
