Chemical Properties
Calcium carbonate is precipitated when carbon dioxide is passed through a clear solution of calcium hydroxide in water. The lime water turns milky serving as a test for carbon dioxide liberation. On passing excess of CO 2 gas the milky ness disappears due to the formation of calcium bicarbona..

In a chemical reaction there is a rearrangement of particles. This rearrangement of particles, results in drastic changes in the properties of the substances. For e.g., sodium and chlorine are very reactive elements. When they combine, an electron is shifted from the sodium atom to the ch..

Rate of Chemical Reactions
Everyday experience tells us that chemical reactions take place in widely varying rates. Infact rates of various reactions vary from very slow to very fast. Some reactions are so rapid that they occur as soon as the reactants are mixed. For example, the reactions involving ionic species ..

As acids and bases are highly corrosive and reactive substances it is important to understand their reaction and responses on substances commonly found around us. It helps us to understand the outcomes of using them in daily lif..
Acids, Bases and Salts Summary
>A strong base dissociates completely in water Example: Sodium hydroxide A weak base dissociates partially in water Example: Ammonium hydroxide In neutralization reaction acids and bases neutralize each other to form corresponding salts and water Acidic and basic solut..
Chemical Fertilizers
Chemical Fertilizers - These are nutrient supplements for plants manufactured in fertilizer factories from chemicals. They are nutrient specific i.e., they may provide only nitrogen, only phosphorus or only potassium to the soil. They are often used when a particular nutrient is..

Hydrogen is a combustible gas, but does not support combustion. In presence of air or oxygen it burns with a blue flame to form water. If hydrogen is mixed with oxygen, it explodes with a pop sound. A Jet of Hydrogen Burns in Air with a Pale-blue Flame. The Steam is Condensed to Water on ..
