Power laws simply explained - power, base, exponents - same base - analysis. A power consists of a base and an exponent, the exponent is often written as a superscript. The power laws help you calculate. You either keep the base or the exponent. There is also a case where a power is put in brackets.

An acid is a substance that will dissociate in water to give a proton (or H+ ion) and a conjugate base. An acid is considered to be strong if dissociation nears 100%, and weak if dissociation is usually less than 1%. In this lesson, we will learn about strong alkalis and weak alkalis. An alkali
