Click hereto get an answer to your question Name the four chemicals that are obtained from common salt and write their molecular formulae.
. There are two salts that are used in the creation of the black and white photography which are Silver chloride and the silver Iodide. This is because silver salts in particular silver halides are light sensitive compounds. Photographic paper made at home.
Talbot knew that silver-chloride could be used for photographic printing but it couldnt be coated onto paper. For eg- Potassium sodium tartrate KNaC 4 H 4 O 64H 2 O also known as Rochelle salt. On the other hand the silver bromide is found naturally as the mineral bromargyrite.
Salt is white odorless and it has a salty taste. Chemical names for other types of salts include magnesium sulfate commonly known as Epsom salt potassium iodide a salt commonly used. Silver chloride compound occurs naturally as a mineral chlorargyrite.
Potassium permanganate has the violet color of permanganate anion. This salt can neutralise the excess acid secreted by the stomach. Salts are a type of ionic compound that derives its chemical name from the anions and cations it contains.
Punineep and 292 more users found this answer helpful. They supply all sorts of chemicals for alternative processes. The choice of a salt in the lab is determined primarily by how acid or basic the chemical is the pH the safety of the ionized form the intended use of the drug how the drug is given for example by mouth injection or on the skin and the type of dosage form such as tablet capsule or liquid.
Mixed Salts The salt that consists of a fixed proportion of two salts often sharing either a common cation or common anion is known as mixed salt. Many photographic chemicals use non-biodegradable compounds such as EDTA DTPA NTA and borate. Food manufacture of chemicals.
Along with silver chloride it is being widely used in black and white photography and films. While not a list per se it would be a way for you to compile such a list. The predicted hazards and gas byproducts for each reactive group pair will be displayed as well as documentation and references that were used to make the reactivity predictions.
This is the time when it is advisable to use sodium carbonate because when the salt is added to the dye it helps the dye in bonding to the fabric effectively. Sodium Chloride or Common Salt NaCl Used in cooking food as well as for cooking gas. Nitric acid always produces salts that end in nitrate and contain the nitrate ion NO3-.
Use the links below to find out how this reactive group interacts with any of the reactive groups in the database. Thus the correct answers are silver chloride and silver bromide. Silver Chloride AgCl and Silver Bromide AgBr are the salts which are very commonly used in photography.
Sodium bicarbonate or baking soda This is also another type of salt that has many other uses outside the kitchen. Name the four chemicals. Potassium manganateVII can kill bacteria and hence is suitable for use as an disinfectant.
All potassium K ammonium NH 4 and sodium Na salts are soluble in water H 2 O. Name of Salts. On the website they list the chemical and its use in photography--many salts and toners.
The most light-sensitive compounds are silver salts and the photography that prospered in the second half of the nineteenth and throughout the twentieth century was based almost entirely on. Nitrites nitrates and bicarbonates can be dissolved in water. EDTA and other polyamine polycarboxylic acids are used as iron ligands in colour bleach solutions.
Learn about the definition chemical formula and characteristics. By exposing them to sunlight through patterned masks. Silver halides are quite sensitive to the light and when the photon particles fall they start photochemical reactions to complete the job.
EDTA DTPA and NTA are very often used as chelating agents in all processing solutions particularly in developers and washing aid solutions. Potassium dichromate is orange by virtue of the dichromate ion. Its compounds make salt one of the most important materials in the industry as it is used for the chemical synthesis of more than 50 of chemical products.
Copper sulfate is blue because of the copper II chromophore. The salt helps to make internal soft organs like intestines appear on X-ray films. The two chemicals combine to form silver-chloride in the paper.
Hydrochloric acid always produces salts that end in chloride and contain the chloride ion Cl-. In chemistry a salt is defined as an ionic compound formed when a positively charged ion is bonded to a negatively charged ion. Barium sulphate is used to make barium meals for patients who need to take an X-ray of their stomach.
In a stroke of genius he first applied ordinary salt-water and in a second step sensitized the paper with silver-nitrate. The thermal decomposition reaction of calcium sulphate gypsum is used in black and white photography. Used as a preservative in pickles and in curing meat and fish.
For example the chemical name for table salt is sodium chloride which is represented by the chemical formula NaCl. All metallic oxides metallic carbonates hydroxides phosphates and sulphides are insoluble in water. Join Login Class 10 Chemistry Acids Bases and Salts Study of some important salts Name the four chemicals that are obtaine.
The chemical industry is by far the largest consumer of salt. Manufacture of paint and rubber tires. Salt used as an essential building block in the chemical industry.
They are obtained by the combination of two different salts crystallized in the same ionic lattice. Cobalt nitrate is red owing to the chromophore of hydrated cobalt II Co H 2 O 6 2.
