In this article we will discuss about some chemical compounds like acid, base and buffers. Acid and Base: An acid may be defined as a substance which, when dissolved in water, produces hydrogen ions [H+] or in other words, it is the compound of electronegative element with ionisable hydrogen [H+]. Similarly a base or alkali […]

The following article will guide you about how to calculate pH of a solution. Also learn about the physiological importance of maintaining pH. pH: The pH of a solution is defined as the negative logarithm (base 10) of the hydrogen-ion concentration, i.e., pH = -log [H+] or pH = log (1/[H+]). Calculation of pH: For […]
