Action of Alkali Metals
When sodium, potassium or lithium is reacted with dry ethanol, the hydrogen atom of the hydroxy group is replaced by the metal atom to form alkoxides. Hydrogen is liberated in the process. The reaction takes place with effervescence. This reaction also serves as an identifiction test..

Sodium hydroxide is commonly called caustic soda because of its corrosive action on animal and vegetable tissues. Large quantity of sodium hydroxide is prepared by electrolytic process called the 'Chlor-alkali process'. Here, chlorine gas is given of at the anode and ..
Salting out of Soap
Saponfication is complete when we see a slight excess of the alkali in the transparent reaction mixture. Common salt or brine is then added to precipitate soap and heating is continued. Soap forms in the upper layer as a thick mass. This is known as salting out of soap . The u..
Abundance and occurrence
Alkali and alkaline Earth metals are the most violently active of all the metals. These occur in the combined form with halide, sulphate, carbonate, silicate ions, etc. and are not found in the free state in nature, as these are readily oxidized. A number of alkali and alkaline..
Carbonating tower
Carbonation of ammoniacal brine is carried out on the principle of counter-current. The clear ammoniacal brine solution is pumped to the top of the tower. This flows downwards and meets a current of CO 2 introduced from the bottom of the tower at a pressure of 1-2 atmosphere. ..

Effluents from paper mills, textile mills and leather industries contain many toxic substances such as lignin, chlorine, ammonia, heavy metal salts, acids, alkalies, etc. The polluted water needs to be suitably treated before discharging into river or running water. First, the solid and ..
Propane-1,2,3-trial (Glycerol)
A trihydric alcohol, glycerol is a constituent of oils and fats. Oils and fats are tri esters of long chain fatty acids. On hydrolosys in presence of an alkali, the tri esters yield glycerol and the fall of the carboxylic acids. Glycerol is obtained as a by-product in the soap industry pr..

Hydrogen is the most abundant element in the universe. Hydrogen is also the lightest element in the universe. It has a vapour density of 1, which is 14.4 times lighter than air. Hydrogen is absent in the free state in the earth's atmosphere. But in the combined state it is found in water, a..

Tutor has given me a lot of good advise for my study. They has the package to be the best and the best teachers! they are not just have the teaching skills and understanding the subject matters as well. Thank you.
Really good tutors. Real helpful and made things easy to understand. Tutor vista is a real online tutoring company
Turtors are so good, and patient and most important knows their stuff. They really tutor in a very professional way. Their system is unique and they really knows how to explain and made sure you undertand. They even put stuff from a book into the white board, just to show me how the process of my question - Paul
I really liked this sessions becuse i am able to understand some problems that i didn't originally understand. This sessions was a great oppurtiunity for me to learn. I really enjoy being with tutorvista!!!!!!!!!
