A perchlorate (ClO4 - ) ion-selective electrode immersed in 50.0 mL of unknown perchlorate solution gave a potential of +358.7 mV. When 1.00 mL of 0.050 M NaClO4 was added, the potential changed to +346.1 mV. Assuming that the electrode is ideal, find the concentration of ClO4 - in the unknown.

Darla claims that the first periodic table developed by mendeleev was not completely accurate, so it is not useful at all. harmony argues that it establish the periodic table we use today, making it more credible. who is correct and why? darla is correct, because a model that has any mistakes should be thrown out. darla is correct, because a good model would not need to change. harmony is correct, because mendeleev’s model had all of the information correct in the first version. harmony is correct, because mendeleev’s model made predictions that came true.
