The selectivity coefficient, K+,H+ , for a K+ ion-selective electrode is 0.00575 . When the electrode is placed into a 7.38×10−5 M K+ solution at pH 6.58 , the potential is −0.168 V vs. SCE. If the pH of the solution is lowered to 1.23 and the ionic strength is kept constant, what is the potential of the electrode? Assume =1 for the electrode.

a) the particles of the chair are strongly held together.

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
