A50.0 ml sample of an acid, ha, of unknown molarity is titrated, and the ph of the resulting solution is measured with a ph meter and graphed as a function of the volume of 0.100 m naoh added. at which point on the titration curve is [a-] closest to twice that of [ha] ?

i think a, hope it .

explanation:

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
