Study Notes
Alkali Metals Overview
- Alkali metals belong to Group 1A of the periodic table.
- They are known for being the most reactive metals.
Hydrogen Facts
- Hydrogen is the most abundant element in the universe.
- Also referred to as "inflammable air."
- Protium is the most common isotope of hydrogen, followed by deuterium (heavy hydrogen) and tritium (radioactive hydrogen).
Lithium Insights
- Lithium is recognized as the lightest metal and the lightest element overall.
- Pharmaceutical uses include being a depressant and a diuretic.
- Non-pharmaceutical applications encompass its use in heat exchangers for air conditioning.
- Important lithium compounds include:
- Lithium Bromide: depressant.
- Lithium Carbonate: used for treating mania.
- Lithium Fluoride: used in the manufacture of ceramics.
- Lithium Stearate: utilized in cosmetics, plastics, and powder metallurgy.
- Lithium Hydroxide: absorbs CO2.
- Lithium Chloride: contributes to the manufacture of mineral water.
Sodium Characteristics
- Sodium, also known as natrium, is essential for various applications.
- Primary pharmaceutical uses include fluid retention treatment.
- Sodium compounds vary widely, consisting of 19 different types, including:
- Sodium Acetate (Sodium ethanoate): diuretic and antacid.
- Sodium Bicarbonate (Baking soda): carbonating agent, but can cause systemic alkalosis and rebound hyperacidity.
- Sodium Dihydrogen Phosphate: used as a cathartic and in enemas.
- Sodium Metabisulfite (Sodium pyrosulfite): acts as a water-soluble antioxidant.
- Sodium Chloride (NaCl): known as rock salt or table salt; used as an electrolyte replenisher.
- Sodium Hydroxide (Caustic soda): used in making hard soap.
- Sodium Iodide: treats goiter and acts as an expectorant and antifungal.
Additional Sodium Uses and Compounds
- Sodium Lactate: functions as an antacid and diuretic.
- Sodium Nitrate (Salitre): serves as a vasodilator and preservative, and treats cyanide poisoning.
- Sodium Nitrite (Chile salt peter): used in explosives and recognized as the oldest known inorganic fertilizer.
- Sodium Thiocyanate: acts as a hypotensive agent.
Important Sodium Functions
- Sodium sulfate is known as Glaubers salt.
- Sodium tartrate: serves as a primary standard for water content determination in various analyses.
