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 and basicity of a solution.Acids have lower pH than bases whereas the ne...
Not a buffer Buffering Solution: A buffering solution maintains a constant pH by eliminating the effects of a change in the concentration of H+ ions. This is achieved through two equilibrium reactions. Answer and Explanation:1 Buffers require a weak...
