Which of the following is dissolved in water?
[BCECE 2005]
Options:
A) White Phosphorus
B) Sodium is an essential mineral that plays a key role in maintaining fluid balance, nerve function, and muscle contractions. It is also necessary for the proper functioning of the heart and is involved in the transport of nutrients across cell membranes. A deficiency in sodium can lead to hyponatremia, while excessive intake may contribute to hypertension. The recommended daily intake varies by age, sex, and activity level, with athletes and individuals in hot climates often requiring higher amounts. Sodium is commonly found in table salt (sodium chloride) and is also present in various foods such as processed meats, dairy products, and vegetables.
C) Potassium is an essential mineral that plays a key role in maintaining fluid balance, nerve signaling, and muscle contractions. It also helps regulate blood pressure and supports proper functioning of the heart. A deficiency in potassium can lead to symptoms such as fatigue, muscle weakness, and irregular heartbeats. Good dietary sources of potassium include bananas, oranges, spinach, potatoes, and tomatoes. The recommended daily intake for adults is approximately 2,600–3,400 milligrams, depending on age and gender. Excessive intake, typically from supplements, can cause hyperkalemia, which may result in serious health issues.
D) Calcium is an essential mineral that plays a crucial role in maintaining strong bones and teeth, supporting muscle function, and facilitating nerve signaling in the body. It is also vital for blood clotting and the proper functioning of the heart. A deficiency in calcium can lead to conditions such as osteoporosis, while excessive intake may result in health issues like kidney stones. Good dietary sources of calcium include dairy products, leafy green vegetables, and fortified foods. The recommended daily intake varies by age, gender, and life stage, with adults generally needing around 1000-1300 milligrams per day. Calcium absorption is enhanced when consumed with vitamin D, which helps the body utilize calcium more effectively.
