For a triprotic acid (H3G) has pKa1 = 2.10, pKa2 = 6.10, pKa3 = 10.10. (A) what's the conjugated base of HV2- ?
(B) At what pH the concentration [H3V-] = [V2-]?
(C) what reagent/s are needed to prepare an pH 10.00 buffer, assuming you have access to strong acid and strong base in addition to the H3V? Describe qualitative how you would prepare the needed pH buffer, and what are the criteria to evaluate whether the pH buffer is good/effective.

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.

the answer is 0.8m.

the elements that are used in nuclear fission and their products are much heavier than helium.
