∙ 13y ago
adding these two compounds serves two purposes. they are: -
i) they help the washing powder to remain dry and
ii) to maintain the alkalinity of the washing powder

Formula for aqueous hydrogen silicate?
Adding one hydrogen to silicate will give you [HSiO3]-1. In order to get an aqueous form of hydrogen silicate, two hydrogens must be added, giving H2SiO3.
What colored coating is formed on adding zinc granules to freshly prepared ferrous sulphate solution?
A grayish coating is formed.
If you add anhydrous sulphate to water do you get a chemical reaction?
yes you do. this is because the anyhdrate was white (crystals) and after adding water, it turned blue
How can you test a solution for the barium ions?
Acidify the given solution with a few drops of concentrated HNO3 followed by the addition of 4 mol dm-3 sulphuric acid or ammonium sulphate. A white precipitate implies that there are Barium (II) ions present in the solution. The objective of the test give above is to recognize the Barium(II) ions as the white precipitate of barium sulphate which is not soluble in most of the solvents. Adding a sulphate solution at first might cause distractions as other cations such as strontium also make white precipitates with sulphate ions. Those other precipitates dissolve in dilute nitric acid.
How dou you show the presence of both iodide and sulfate in a mixture?
You can show the presence of Sulphate in a mixture by adding barium chloride solution followed by dil HCl. A white precipitate that does not dissolvev in dil HCl indicates the presence of sulphate ioins. Ba2+ (aq) + SO4^2- (aq) ---------> BaSO4 (s) Iodide ions can be shown by adding to the suspected iodide a solution of lead nitrate where upon a brilliant yellow ppt is thrown down Pb2+ (aq) + 2 I- (aq) --------> PbI2 (aq) Also addition of silver nitrate will give a yellow ppt which is insoluble in ammonia solution. Ag+ (aq) + I- (aq) ----------> AgI (s)
What is the good substitute for copper sulfate when mixing it with NAOH?
Please indicate the purpose of adding the copper sulphate and resubmit your question.
What is the purpose of adding dilute hydrogen sulphate while electrolysis of water?
You add electrolytes (i.e. hydrogen sulphate) to increase the electrical conductivity of your solution. This speeds up the charge transport and thus the reaction speed at the electrodes.
How would you separate lead sulphate from a mixture of lead sulphate and lead chloride?
by adding hot water
Formula for aqueous hydrogen silicate?
Adding one hydrogen to silicate will give you [HSiO3]-1. In order to get an aqueous form of hydrogen silicate, two hydrogens must be added, giving H2SiO3.
What effect does adding sugar to dish washing liquid have on the bubbles?
Adding sugar to dish washing liquid will increase the amount of lather and bubbles.
How can you get zinc chloride by adding zinc sulphate into sodium chloride?
The reaction is not possible.
Did you ruin the engine by adding low silicate coolant in your 1999 Chevy Camaro?
What does your owner's manual say to use? If low silicate is not listed then drain and refill with the proper coolant.
When adding aluminum sulphate to swimming pool should the filter be running?
Add the aluminum sulphate to the pool. Run the filter for two hours. Wait overnight to vacuum the bottom of the pool.
What produces white precipitation when reacted with aqueous barium nitrate?
Adding a solution of Sodium Sulphate to aqueous Barium Nitrate will produce a white precipitate of Barium Sulphate with Sodium Nitrate remaining in solution.
What is the purpose of adding sugar to cookie dough?
The purpose is to make it sweet.
What colored coating is formed on adding zinc granules to freshly prepared ferrous sulphate solution?
A grayish coating is formed.
How could you separate a preparation of lead sulphate obtained by adding sulfuric acid to a solution of lead nitrate?
Filtration or centrifugation.
