What would you predict about a chemical that has a hydrogen ion concentration of 1×10 to the -12 it is basic it is acidic it is a buffer it has a ph of 7

It is basic.

Explanation:-

Given hydrogen ion concentration [H+] = 1×10^-12

Using the formula

pH = - log [H+]

= - log [ 1 x 10^-12]

= 12

Since the pH is more than 7, the chemical is basic

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
