Logarithms
If a > 0 such that a y = x then y is called the logarithm of x with respect to the = base ‘a’ and written as log a x = ..
Introduction Exponential and Logarithmic Series
We know that log 2 8 is the number to which 2 must be raised to get 8. Therefore, log 2 8 = 3. In general, if a x = y, (a > 0), then we say that log a y = x. If e x = y, then we say that the natural logarithm of y is x and we write log y = x. In other words, if the base of a ..

pH is the negative logarithm of H 3 O + ion concentration in moles/litre pH of water = 7 at 298 K pH of acids = less than 7 pH of bases = greater tha..
The pH Scale
The pH Scale - The strength of acids and bases can be expressed in terms of the concentration of the hydronium ions or hydroxyl ions in a solution. The concentration of hydronium ions in a solution can be expressed as moles of hydronium ions per litre of solution. This is expressed by a t..

It is quite clear that the strength of acids and bases can be expressed in terms of the concentration of hydrogen ions, i.e., hydronium ions (H 3 O + ) or hydroxyl ions (OH - ) in a solution. The concentration of hydronium ions in a solution can be expressed as moles of hydronium ions p..
