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.

Covalent network solids typically have melting points and boiling points. the chemical formula of a network solid indicates in the molecule.

In numbering carbon atoms in the parent chain of a hydrocarbon, why would you number from right to left, rather than left to right

The table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 10 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of the two atoms? both are unreactive. both are highly reactive. a is unreactive and d is reactive. a is reactive and d is unreactive.
