pH and pOH Scales Chemistry JoVE

WebpOH and Other p Scales The pOH scale is analogous to the pH scale but is defined with respect to [OH-] instead of [H 3 O +]. pOH =-log[OH-] A solution with an [OH-] of 1.0 * 10-3 M (basic) has a pOH of 3.00. On the pOH scale, a pOH less than 7 is basic and a pOH greater than 7 is acidic. A pOH of 7 is neutral Notice that p is the mathematical ... WebCreated by. Chemical Concoctions. Use this one-page worksheet during your acid base unit to help you students learn to calculate pH, pOH, [H3O+] and [OH-]. Student will also familiarizing themselves with the universal indicator color scale and where these common substances fit on the pH scale. Answer Key Included. WebExample. Thus, the pH of an acidic solution of HNO 3 (10 –3 M) = 3, a basic solution of KOH having [OH –] =10 –4 M and [H 3 O +] =10 –10 M will have a pH = 10. pH of acids is generally less than 7 whereas for bases it is greater than 7. At 298 K, ionic product of water, K w can be given as:. K w = [H 3 O +] [OH –] = 10 –14. Taking the negative logarithm of … hsa is for
