some basic definitions

Notation: Usually a polynomial is denoted by P(x) and if k is any number then P(k) denotes the value of P(x) at x=k. The degree of a polynomial: If a o ? 0, then the polynomial P(x) or f(x) is of degree 'n' i.e., it is the highest power of the variable x in the rational and integ..

Polynomials - An expression of the form in which a i are numbers belonging to some number system and 'n' is a non-negative integer, is called a polynomial. a i are called the coefficients of if a o 0, the polynomial is said to be of degree ..

Set: A well-defined collection of distinct objects is called a set. Notation of Sets: Capital letters are usually used to denote or represent a set. Representation of Sets: There are two methods of representing a set. (i) Roster Method (ii) Set builder form. Finite an..

A basic salt may also be formed by the partial replacement of the hydroxyl groups of a diacidic or triacidic base, by an acid radical. Basic salts are stronger in their basic nature and show a pH greater than ..

Basic fluxes like lime (CaO), magnesium oxide (MgO) are used to remove acidic gangue such as SiO 2 ...

Borax is slightly hydrolyzed in solution. As boric acid is a weak acid, the solution is alkaline in nature...

A basic salt is formed when there is a higher proportion of the base in the reaction between an acid with a base, than is necessary for the formation of a normal salt. Example: Basic copper carbonate CuCO 3 .Cu(OH) 2 Basic lead carbonate (white lead) PbCO 3 .Pb(OH)..

A buffer solution containing relatively large amounts of a weak base and its salt with a strong acid, is termed as a basic buffer. Such buffers have pH on the alkaline side i.e., pH is higher than 7 at 298 K. The pH of a basic buffer is given by the equation:..

All these hydrides have one lone pair of electrons on their central atom. Therefore, they act as Lewis bases. They can donate an electron pair to electron deficient species (Lewis acids). Down the group, the basic character of the hydrides decreases. For e.g., NH 3 is distinctly ba..
