but sometimes, you have to consider what you're cleaning also. Although household bleach is mostly water, it can still be irritating on its own because of the strong smell. The sodium hypochlorite that is the main ingredient in bleach reacts when it is mixed with either ammonia-based cleaner...
Phenol, when it first react with concentrated sulphuric acid and with ... 02:53 Toluene is nitrated and the resulting product is reduced with tin and ... 07:21 The major product obtained on interaction of phenol with sodium hydrox... 03:00 In the chemical reaction the compounds 'A' and...
Explain what is Gaseous exchange and why is it done and where does it occur? Why is water important to a cell? Why is ATP so full of energy? Why is it necessary to phosphorylate molecules? When sodium sulphate is dissolved in water, why doesn't it release the ions Na^+, S_...
When an ionic salt is added to the water then it dissociates in its constituents ions and these ion gets hydrated by the water molecules. The process of surrounding water molecules towards these ions is known as hydration.The hydration plays an important role in the solubility of ...
Bromine and mercury are two elements which are liquids at room temperature. Bromine, like its neighbours chlorine and iodine in the periodic ( = of period ) table, has molecules made up of two atoms each. In these liquid elements, the molecules are close together, but not so crowded;they ...
which consists of the chemical elements sodium and chlorine. You probably learned from unintentional play at the kitchen table as a child that if you sprinkle salt into a glass of pure water, the salt disappears after a time; the more salt you add, the longer this takes, and it may...
When electricity is passed through brine itdecomposes to form sodium hydroxide along with the evolution of chlorine gas at anode and hydrogen gas at cathode. Is NaHCO3 a acid? In short, Baking soda or Sodium bicarbonate(NaHCO3) caneither act as an acid as well basebut its aqueous solution ...

The other isthe inorganic snow melting agent, which is mainly composed of chlorine salt,such as sodium chloride, calcium chloride, magnesium chloride and potassiumchloride. The advantage is that it is cheap and is only equivalent to 1/10 oforganic snow melting agents, but its corrosion on ...
