Homogeneous mixture of two substances known solutions,

Here we explain some of the meaning of the solution, the electronic variety, belong to this type of example: - Solution of urea - Solutions sucrose - glucose solution - Solution of alcohol and others.

To study the chemistry is a very difficult and very complicated, we must require a calm mind, focus, and should Bener really understand the lesson. Well .. now we enter the first prefix for a solution.

Solution is a homogeneous mixture of two or more substances which dissolve each other and each of the constituent substances can not be distinguished in theory or physical.

Solution consists of the solute and solvent. Based on the electrical conductivity, the solution divided into two kinds, namely: Solution of non-electrolytes and electrolyte solutions.

Electrolyte solution is a solution that can deliver electrical current.

This solution is distinguished by:

1. Electrolyte STRENGTH
Strong electrolyte solution is a solution that has a strong electrical conductivity, because terlarutnya substance in a solvent (usually water), completely changed into ions or alpha = 1.

Classified as strong electrolytes are:
a. Strong acids,
such as: HCl, HCl03, H2SO4, HNO3 and others.
b. Strong bases, ie class bases of alkali and alkaline soil,
such as NaOH, KOH, Ca (OH) 2, Ba (OH) 2 and others.
c. These salts are easily soluble,
such as NaCl, KI, Al2 (SO4) 3 and others

2. Electrolyte WEAK
Weak electrolyte solution is a solution of a weak electrical conductivity with the degree of ionization rates for: O <1.

Classified as weak electrolytes:
a. Weak acids such as CH3COOH, HCN, H2CO3, H2S, etc.
b. Weak bases such as NH4OH, Ni (OH) 2 etc.
c. These salts are difficult to dissolve, such as AgCl, CaCrO4, PbI2 etc.

Non-electrolyte solution is a solution that delivers an electric current can not, because terlarutnya substances in the solvent can not produce ions (not mengion).
