Description : This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1900 Excerpt: ...OXIODIDUM. (Oxy-iodide of Bismuth.) OBiI=350.5. Bismuth subnitrate 12 parts Potassium iodide 7 parts Distilled water 15 parts Mix and digest together in a bottle for an hour, shaking occasionally. Then transfer to a filter, and wash with warm water until the washings are tasteless. Drain, and dry between filterpaper. Reaction. BiON03.H20+KI=KXVf BiOI+H, O. O. Kaspar's Method. Crystallized normal bismuth nitrate 94.5 Gm Distilled water 30 liters Nitric acid, the least quantity sufficient to dissolve the bismuth nitrate in the water. Make a solution: Potassium iodide 33.2 Gm Distilled water 3 liters Dissolve. Mix the two solutions. When the brown precipitate has changed to yellowish and finally to brick-red, wash it by decantation and afterward on a filter, and dry it at about 100 C. B. Fischer's Method. Crystallized normal bismuth nitrate.... 95.4 Gm Glacial acetic acid 120 ml Potassium iodide 33.2 Gm Sodium acetate 5o Gm Distilled water, sufficient. Dissolve the bismuth nitrate in the glacial acetic acid. Dissolve the potassium iodide and the sodium acetate in 2 liters of distilled water. Mix the clear solutions, constantly stirring, pouring the bismuth solution gradually into the other. A yellowish-brown precipitate is formed, which changes to lemon-yellow, and finally to brick-red. Wash the precipitate by decantation and dry it at 100 C. Should be kept protected from light. Description.--A brick-red, micro-crystalline powder, odorless, tasteless, insoluble in water and in alcohol. On ignition it should yield not less than 66 per cent of Bi2O3. Solution of soda, 240 ml, or sufficient. Triturate the bismuth nitrate to powder; add the glycerin and stir until dissolved; then gradually add solution of soda until a precipitate no longer forms, stirring well; was...

Description : Coimbatore is the second Largest Industrial City in Tamilnadu, India. After the introduction of Cell Phones and Development of Mobile Technology, every one used to have a Phone or Mobile. To help to communicate among themselves, this CELFON5G Directory Services are introduced. Every Firm or Person owning a Mobile Phone or Fixed Phone is listed in this CELFON Directories. The Listing gives all 5 communication addresses like 1. Fixed Phone Number 2. Mobile Phone Number 3. FAX 4. Email Address 5. Web Site etc in addition to Postal Address. CELFON Directories are available is 5 Generations (5G) of Media, namely 1.Print Edition 2. Digital Edition for viewing in Mobile Phones 3. Searchable Mobile Apps 4. Web 5. CD etc. Considering the Lakhs of Users in Coimbatore, a single volume of Directory is difficult to handle. So the users are published in 10 Volumes, namely on * SIDCO * Town Hall * Gandhipuram * R S Puram * Thudialur * Ganapathy * Saibaba Colony * Singanallur * Peelamedu * Vadavalli etc. All these Volumes are Printed and Published as per a Time Plan, at regular intervels around the year. Digital Editions are available for each Print Edition. This Digital Edition is containing all volumes as and when published The first among the Series is on COIMBATORE SIDCO Industrial Area. Then followed by COIMBATORE TOWN HALL and COIMBATORE GANDHIPURAM. This Volume contain all the above, as on January 2018. At the time of creation, this Digital Edition is a replica of Print Edition. Later on Contents of this Digital Edition are updated every month with new users. This COIMBATORE CELFON Directory is a single Volume, containing all the Directories Published individualy for above areas. Seperate volumes are also available in Play Books. Updated every Wednesday of the week, containing informations received upto the previous early saturday. Recently updated on 4-4-2018
