Drinking too much water can be a bad thing. If someone sweats heavily and drinks lots of water, his or her sodium levels drop. The resulting “water intoxication” can be fatal. Why is the sodium balance so important?
Gout—a condition that results in joint swelling and pain—is caused by the formation of sodium urate (NaC5H3N4O3) crystals within tendons, cartilage, and ligaments. Sodium urate precipitates out of blood plasma when uric acid levels become abnormally high. This sometimes happens as a result of eating too many rich foods and consuming too much alcohol, which is why gout is sometimes referred to as the “disease of kings.” If the sodium concentration in blood plasma is 0.140 M, and Ksp for sodium urate is 5.76 * 10 - 8, what minimum concentration of urate would result in precipitation?
Solutions conduct electricity, if there are charged particles or ions present. Our body contains ions, too. Thus, solution containing ions are called electrolytes. Why do you feel thirsty after playing or working outside? Sometimes, you suffer from cramps or headaches, in extreme cases, you may even experience vomiting and nausea. These are symptoms of electrolyte imbalance in the body. Suggest ways or recommendations that can be given to a person who experience electrolyte imbalance.
