WebpH AND POH Name The pH of a solution indicates how acidic or basic that solution is. pH range Of 0-7 acidic 7 neutral 7-14 basic Since [OH-I at 250 C, if IH+I is known, the [OH.] can be calculated and Vice versa. pH - log [H*] POH = — log [OH-I Together, pH + POH = Complete the following chart. Soif = 10-6M, pH = 6. so if [OH-I - M, pOH = 8. 14. WebpOH = −log [OH −] = −log (4.9 × 10 −7) = 6.31 At this temperature, then, neutral solutions exhibit pH = pOH = 6.31, acidic solutions exhibit pH less than 6.31 and pOH greater than 6.31, whereas basic solutions exhibit pH greater than 6.31 and pOH less than 6.31. Web“pH” is an abbreviation for “potential of hydrogen”. It is a unit of measurement that stands for the concentration of hydrogen ions that are within a solution. When an acid or base is mixed with water, the compound disassociates into ions. In acids one of the ions is a hydrogen ion (H+), In acids, one of the ions is a hydroxide ion (OH-). hbrpeknx0203al

WebpOH and Concentration in Bases The pOH scale is essentially the pH scale, but backwards. This is shown in the following image: On the pOH scale, all bases are below 7. A strong base would be between 1 and 3, while a weak base would be between 4 and 6. 7 is still neutral and above 7 is an acid.
