The volumes between successive equivalence points in the titration of a polyprotic acid are theoretically equal. Consider again the titration of citric acid (H3C6H5O7) as in question 1 of the Pre-laboratory Questions where a titration required 15.3 mL of 0.180 M NaOH to reach the first equivalence point. How many mL of this base would be required so that the titration solution was essentially a solution of sodium citrate (Na3C6H5O7)?

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.

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