SILVER NITRATE is a transparent colourless or white crystal. Silver nitrate has powerful germicidal and antiseptic power. We have became the largest integrated Silver Nitrate manufacturer and supplier who can provide different kinds of Silver Nitrate that has well tested as per Analar Standards, IP, BP & USP Standards as well.Application: Silver Nitrate used in vacuum flask refill and mirror manufacture, silver plating, printing, corrosive agent in medicine, hair dye, analytical agent, preparation of other silver salt and colourfast ink. Silver Nitrate, Crystal, Reagent, ACS is an inorganic compound with the formula AgNO3. Silver nitrate is an extremely versatile analytical laboratory reagent for both the qualitative and quantitative determination of halides, carbonates, hydroxides, sulfides and phosphates. We provides solid Reagent ACS grade silver nitrate for preparation of analytical laboratory reagent solutions. As an ACS grade Reagent, Spectrum Chemical manufactured Silver Nitrate is used as the quality reagent in standard testing to which other substances are graded. It has met the toughest regulatory standards for quality and purity.Dose: Silver Nitrate Helps to test Halogen Family Chlorine, Bromine and Iodine ions due to its characteristic change of colour as follows ::: Silver Nitrate + Chloride = White,  Silver Nitrate + Bromide = Pale Yellow,  Silver Nitrate + Iodide = Yellow.   Silver Nitrate also helps to find presence of Carbonate, Hydroxide, Sulfide and Phosphate ions. For example: Pale Green=Carbonate, Brown=Hydroxide, Black=Sulfide.   Silver Nitrate is used in Oil Fields to determine the amount of Chloride ions in water and drilling fluids.Note: ALWAYS dissolve Silver Nitrate powder into Distilled Water. NEVER use Tap Water when dissolving Silver Nitrate powder – it will turn ‘milky’ (dilute Silver Chloride).

Potassium Thiocyanate solution can be used in titrations involving Silver Nitrate solutions. Chloride, Bromide and Iodide can be determined indirectly this way by adding excess Silver Nitrate solution to the sample containing the Halide, thus precipitating the Halide, and titrating the excess Silver Nitrate with Potassium Thiocyanate titrant using a Ferric Alum Indicator. Application: The reactions for this Volhard titration are: X- + excess AgNO3 → AgX (precipitate) + AgNO3 X = Cl, Br, I KSCN + AgNO3 → AgSCN (white precipitate) + KNO3 excess SCN- + Fe3+ → [FeSCN]2+ (red complex at endpoint)Dose: Potassium Thiocyanate solution can also be used to standardize Mercuric Nitrate solutions using Ferric Alum as the indicator: 2 KSCN + Hg(NO3)2 → Hg(SCN)2 (white precipitate) + 2 KNO3 excess SCN- + Fe3+ → [FeSCN]2+ (red complex at endpoint) Ammonium Thiocyanate and Potassium Thiocyanate solutions can be used interchangeably in these determinations.Note: Potassium Thiocyanate Potassium Thiocyanate Chemical Formula KSCN Formula Weight 97.18 Equivalent Weight 97.18 (Molar = Normal) CAS No. 333-20-0

RESIDUAL CHLORINE TEST KIT,COLOUR COMPARATOR,Application: Chlorine Range : 0.1, 0.2,0.4,0.7,1&2ppm as Chlorine. Directions for use: 1. Add 2 drops of Chlorine Reagent in the test jar. 2. Pour water sample upto 10 ml mark and mix well.  Wait for 5 minutes. 3. Now rinse the empty comparator tube with above solution and fill upto the half level of the comparator tube. 4. Insert this tube in sample slot of comparator. Compare the devloped colour with standard comparator colours. 5. Note down the ppm level of Chlorine as CL2Dose: Note:

Lead Test Kit  results a deep orange colour indicates the presence of lead. We are manufacturer of Leadt Test Kit for WATER.  Lead is seldom found uncombined in nature, it is mostly found in the form of Lead Oxides. Lead Oxides includes all oxides of Lead (Pb). In Lead Oxide category, all three lead Oxides are subcategorized as Lead Sub Oxide, which is a mixture of Lead Oxides & free Lead Powder and commercially called as Grey Oxide secondly reddish oxide of lead as Red Lead used as a pigment in paints, glass and ceramics thirdly a Yellow Lead Oxide, also called Lead Monoxide and commercially called Litharge.Application: Test for Lead in water: Reagents: Ammonia-Sodium sulphite solution Dithizone solution Chlorofrom Procedure: . 20 drops of sample was taken in a beaker. . Adding 15 drops of Ammonia-Sodium sulphite solution. . Adding 2 drops of Dithizone solution. . Adding 20 drops of chloroform to the above mixture. . Shake well and allow the phases to separate. . Note the colour of thte lower layer. Result: A deep orange colour indicates the presence of lead. (This test can detect upto 4 x 10-6 ppm of lead)Dose: Procedure: . 20 drops of sample was taken in a beaker. . Adding 15 drops of Ammonia-Sodium sulphite solution. .
