Question Answer
Strong Ammonia SolutionSpirit of Hartshorn
Strong Ammonia SolutionPossesses unshared pair of electrons, thereby serving as a ligand in forming soluble complex ions with many metal cations
Haber ProcessNitrogen and hydrogen are mixed in volume proportions of 1–3 under high pressure (bet 100 and 1000 atm), passed through a promoted iron catalyst at a temp of 400o to 550oC.
Strong Ammonia Solution:USESBronsted base
Strong Ammonia Solution:USESUsed in the manufacture of HNO3 and NaHCO3
Calcium HydroxideSlaked lime, lime water, hydrated lime, Milk of Lime
Calcium Hydroxide-SlakingManufactured by careful addition of a limited amount of H2O to Lime (CaO)
Calcium HydroxidepH = 12.3, capable of neutralizing acids
Calcium Hydroxide Indicator: phenolphthalein
Calcium Hydroxide:UsesFluid electrolyte /Antacid
Calcium Hydroxide:UsesTopical astringent and protective (Calamine lotion)
Calcium Hydroxide:UsesManufacture of soap

Question Answer
Calcium Hydroxide:UsesThe solution may be added to babies’ formulae for the purpose of preventing curdling of milk in the presence of acid gastric contents, thus promoting digestibility of the milk.
Potassium HydroxideCaustic Potash
Potassium HydroxideVery deliquescent – Rapidly absorbs moisture and CO2 from the air – Strong base, have a similar property with NaOH
Potassium HydroxideIndicator: methyl orange
Potassium Hydroxide:USESIt rapidly destroys tissues (escharotic properties)
Potassium Hydroxide:USESUsed to make soap
Sodium CarbonateMonohydrated Sodium Carbonate
Sodium Carbonate– Hydrolysis – Hydration-– Neutralization (basis for assay: H2SO4) – Double decomposition – Precipitation
Sodium Carbonate:Method of ManufactureMethod of Manufacture: Solvay Ammonia- Soda Process
Na2CO3 (anhydrous)Soda Ash

Question Answer
Sodium Carbonate (sal soda, washing soda, soda crystals)Na2CO3.10H2O
Sodium Carbonate(basis for assay: H2SO4)Neutralization
Sodium Carbonate:Uses– Electrolytes – Antacid – Systemic alkalizer
Sodium Carbonate:Uses– Used to make acidic form of drugs; source of carbonate
Sodium Carbonate • Systemic Alkalizer–By absorption (following neutralization of the gastric acid contents), from the GIT, they enter the blood and raise the level of the alkaline reserve.
Sodium Carbonate • Systemic Alkalizer Having raised the alkaline reserve the body acts to rid itself of the alkalinity, and excretes the excess alkali renally, thus throwing the burden to the excess kidney.
Sodium HydroxideCaustic Soda, Soda Lye

Question Answer
Sodium HydroxidePractically identical to those of KOH – Very deliquescent – Primary difference: contains nmt 3.0% Na2CO3 – Should not be stored in glass-stoppered containers
Sodium HydroxideUsed to manufacture soap
Sodium HydroxideCorresponds to the tests for Sodium
Sodium Hydroxide :UsesCaustic: damages tissue
Sodium Hydroxide :UsesAlkalinizing agent to form soluble sodium salts of various drugs
Sodium Hydroxide :UsesSaponifying agent
Soda Lime:Calx SodicaMixture of Ca(OH)2 and NaOH or KOH or both.
Soda Lime:Calx SodicaUSP states that it may contain an indicator which will not react with the common anesthetic gases, and which will change color when the absorption capacity of the soda lime for CO2 is exhausted.
Soda LimeUSP states that it may contain an indicator which will not react with the common anesthetic gases, and which will change color when the absorption capacity of the soda lime for CO2 is exhausted.
Soda LimeUses – Metabolism test – Anesthesia – Oxygen therapy
