Study Notes
Hydrogen
- Red container signifies hydrogen storage.
- Production methods include Messerschmidt process and Lane process.
- Most abundant and lightest element in the universe.
Lithium
- Lightest metal in existence.
- Unique property: boiling point exceeds 100°C among metals.
- Applications include heat exchangers in air conditioning systems.
- Used therapeutically to treat bipolar disorder, addressing manic and depressive states.
- Manic state characterized by heightened emotions; depressed state involves low moods.
- Interaction with sodium: increased lithium levels result in decreased sodium levels, leading to hyponatremia.
- Important medical advice: sodium intake should not be restricted during lithium therapy.
Sodium
- Derived from "natrium," meaning nature.
- Aldosterone hormone is key regulator of sodium levels.
- When aldosterone is activated, sodium and water levels rise while potassium decreases, potentially causing hypokalemia.
- Symptoms of hypokalemia include muscle weakness and paralysis.
- If aldosterone is blocked, sodium decreases while potassium increases, along with water retention.
- Significant potassium-rich fruits include avocado and banana.
- Sodium is the predominant extracellular cation in the body.
Potassium
- Potassium is the primary intracellular cation.
- Key concept: PISO (Potassium Inside, Sodium Outside) highlights the distribution of these ions across cell membranes.
