The Ka1 is 1.4 * 10^-2 and the Ka2 is 6.4 * 10^-8.pH of a Solution:The pH of a solution is calculated as the negative logarithm value of the toal hydrogen ion concentration in a solution. it determines the degree of acidity ...
What does the pH measure?Understanding pHIn many scientific disciplines, the p- operator calculates the negative logartihm of an expression. This is particularly help for calculating acid concentrations as they are generally very low in value. The pH of a substance essentially gives the negative ...
