At high ph, most ph electrodes will show a significant response to cations other than h. consider the following ph measurements: ph =1.00 for a solution with (h+ 0.10 m and (na+) 0.10 mph = 9.00 for a solution with [h+]=º0 x 10-11 mind (na+)=0,10 m. estimate the selectivity coefficient kh+,n,+ number
