Potassium sodium tartrate balance eq & phys prop

2KHC4H4O6 + Na2CO3 + 6H2O = 2KNaC4H4O6 x 4H2O + CO2 white crystalline powder or as a large, colorless, transparent, rhombic prisms

sodium citrate and phys prop

3NaHCO3 + H3C6H5O7 x H2O = Na3C6H5O7 +3CO2+2H2O colorless, monoclinic crystals or as a white, odorless, crystalline powder

Theoretical results:Potassium Acetate (KCH3COO)

FeCl3 + acetate = deep red color (due to: ferric acetate)

theoritical results: Potassium bitartrate

Flame test - violet heated = potassium bitartrate chars sodium cobaltinitrite (Na3CO(NO2)6) = orange ppt silver nitrite (AgNO2) + ammonin (NH3) = silver mirror

THEORITICAL RESULT - sodium citrate

Flame test = yellow flame CaCl2 (No ppt cold) = heated forms ppt [Calcium citrate]Ca3(C6H5O7) *PPT is insoluble in NaOH but soluble in HCL due to the formation of the water-soluble citric acid and CaCl2 Potassium permanganate (K2MnO4)+ Mercuric sulphate (HgSO4) = WHITE PPT

Potassium bitartrate balance eq and phys prop

KNaC4H4O6 x 4H2O + CH3COOH = KHC4H4O6(down arrow) + CH3COONa + 4 H2O colorless or slightly opaque, rhombic prisms, or as a white, crystalline powder, which is odorless, has a pleasant, acid taste, and is permanent in air.

Boric acid balance eq and phy prop

Na2B4O7 x 10H20 _><_ 4H3BO3 + 5 H2O + 2NaCl transparent, colorless,odorless

sodium acetate balance eq and phys prop

Na2CO3 + 2CH3COOH -> CO2 +H2O + 2 CH3COONa colorless, transparent monoclinic prisms or as a granular, crystalline powder, odorless.

Theoritical uses - Boric acid

astringent, antifungal, antiseptic, opthalmic

Therapeutic use: Potassium Acetate

diuretic and urinary alkalizer and antacid

therapeutic use - sodium acetate

diuretic, urinary alkalizer and systemic antacid or alkalizer

theoritical result - sodium acetate

flame test - yellow flame acidification - vinegar odor FeCl3 - deep red color (due to: ferric acetate)

theoritical results: Potassium sodium tartrate

flame test: violet, yellow (flame test for Na&K) ignited: the salt gives the odor of burnt sugar and leaves a residue of Na and K carbonates Acidification= ppt of potassium bitartrate

Theoritical result-Boric acid

green bordered flame

therapeutic use: Potassium sodium tartrate
