Bases and Alkalis

A base and an alkali base are compounds which react with an acid to neutralize an acid. This reaction forms salt and water. Base is base - water soluble base. A base is a compound that reacts with an acid to neutralize it. Like alkalis, they form salt and water during the reaction. Alkalis turns red litmus paper into blue, which turns the general display paper to blue or purple. The pH of the alkaline solution is higher than that of the alkaline solution feels soap and corrosive.

Pure water is neutral. When acid dissolves in water, the pH will be less than 7 (25 ℃). When an alkali or alkali is dissolved in water, the pH becomes larger than the concentration of 1 molar concentration 1 mol dm - 3 such as hydrochloric acid, and its pH value is 0. Thus, the measured pH is predominantly in the range of 0 to 14, but negative pH values ​​and values ​​above 14 are also entirely possible. Since pH is on a logarithmic scale, the difference in 1 pH unit is equivalent to 10 times the difference in hydrogen ion concentration.

The pH of the alkaline solution is 7 or more. - Until recently people were trapped in everyday life in large and clumsy CRT (cathode ray tube) equipment after moving to the liquid crystal display (liquid crystal display) on the TV screen during that year. Plasma screen makes CRT display obsolete. In this article I will explain in detail how LCD technology and the basic physical principles of plasma work and compare the two to determine which is better suited for your needs.

Strong base: A strong base is a basic compound that deprotonates a very weak acid in an acid-base reaction. Common examples of strong bases are alkali metal and alkaline earth metal hydroxides such as NaOH and Ca (OH) 2. Very strong bases can even deprotonate very weakly acidic C - H groups in the absence of water. Acid-base titration is used to determine an unknown concentration of acid or base by neutralizing an acid or base with a known concentration of acid or base. The stoichiometry of the reaction can be used to determine the unknown concentration. It makes use of the neutralization reactions occurring between acids and bases, and knowledge of how acids and bases respond if their formulation is known.
