level questions: ANALYSIS OF THE IONS FOUND IN COMMERCIAL PREPARATIONS

QuestionAnswer
Zinc oxide (Calamine lotion) mixed with Hydrochloric acidthe both neutralize each other Zn2[Fe(CN6)]Zn
Ferric ionsFe4[Fe(CN)6]3 Prussia blue
Ferric thiocyanate[Fe(SCN)]^4 Blood red color
Phosphate reacts(NH4)3[P(Mo3O10)4] Canary yellow precipitate
When the filtrate is mixed with potassium ferrocyanideproduces a white precipitate.
(When ferric ions of calamine lotion reacts with potassium ferrocyanide) Ferric ionsFE4[FE(CN)6]3 Prussian Blue
Ferric thiocyanate[Fe(CCN)]^4 Blood-red color
Fleet enema reacts with Nitric acid, Solid Tartaric acid and ammonium molybdate solutionForms white precipitate Canary yellow precipitate
Alum uses1 Water purification 2 Leather tanning 3 Dyeing, fireproof textiles 4 Baking powder 5 Deodorant 6 Aftershave treatment 7 Styptic for minor bleeding from shaving
Alum other names1 Potassium alum 2 Potash alum 3 Potassium aluminum sulfate 4 Tawas
Alum Physical TestColor: White Physical State: Solid Appearance: White Crystalline powder or Octahedral crystals Odor: Odorless
Sodium hydroxide reaction to Aluminum hydroxideAdding Sodium Hydroxide (NaOH) will cause the compound Al(OH)3 to precipitate. However, since Na(OH) is a strong aqueous base and Al(OH)3 is amphoteric, it will redissolve when more strong base is added. the COLOR of the precipitate Al(OH)3 is WHITE
Alum crystal Flame TestProduces lilac color
Baking soda uses1 Reduces acidity in the stomach 2 Removes dirt off materials 3 Pesticide 4 Eardrops, cosmetics, Personal care products
Baking soda Physical TestColor: White Physical state: Solid Appearance: White Crystalline powder Odor: Odorless
Baking Soda Flame Test (Sodium)Turns blue gas flame to YELLOW COLOR
Ions present in Baking Soda (Sodium Bicarbonate)1 one sodium cat ion 2 one bicarbonate an ion
Chlorine Bleach uses1 Disinfectant 2 Remove stains 3 Whiten fabrics
Laundry Bleaching agent Physical TestColor: Light greenish-yellowish tinge Physical State: Liquid Odor: Strong, pungent chlorine odor
Laundry bleaching agent Chemical Test with litmus paperRed litmus turns blue
Add 5ml of 3N HCl to 2ml of the bleaching agent.NaClO + 2HCl --> NaCl + H2O + 2Cl (g) NEUTRALIZATION
Sodium hypochlorite bleaches contain1 one sodium cation 2 one hypochlorite anion
HYDRITE TABLET Physical TestCOLOR WHITE ODORLESS SOLID STATE
HYDRITE TABLET CHEMICAL TESTS - REACTS WITH Nitric acid and Mercurous nitrate TS2KCl + Hg(NO3)2 -> Hg2Cl2 +2KNO3 Produces potassium nitrate and calomel Calomel (White precipitate) Diluted nitric acid is needed
HYDRITE TABLET CHEMICAL TESTS - REACTS WITH Sulfuric acid and Blue litmus paper2KCl + H2SO4 -> K2SO4 + 2HCl produces potassium sulfate and hydrogen chloride which it will form a white precipitate. WHIT PPT - Potassium sulfate Blue litmus paper: no effect
HYDRITE TABLET CHEMICAL TESTS - REACTS WITH Sodium cobalt nitrite3KCl +CoN6Na3O12 -> 3NaCl + 3K + CoN6O12 Produces Sodium chloride which it will produce a white precipitate
HYDRITE TABLET CHEMICAL TESTS - REACTS WITH Alkaline curpic Acetate TSCu(CH3COO)2 + 2KCl -> CuCl2 + 2C2H3KO2 Produces potassium acetate, White precipitate is formed
FLAME TEST OF HYDRITE TABLETLIGHT LILAC COLOR / BLUE PURPLE COLOR
