Question

Suppose an unknown dissolves in water to produce a solution with a pH of 2.4. Which of the following reagents would be useful in obtaining more information about the functional group in the unknown? 6M HCl solution Saturated sodium bicarbonate solution 3 M NaOH solution Explain your answer: Suppose a solid unknown is insoluble in water. Which of the following reagents would be useful in obtaining more information about the functional group in the unknown? 6 M HCl solution 3 M NaOH solution Dilute NH3 solution More than one answer is correct. Explain your answer:

Explanation / Answer

Part1 3M NaOH is used, because others are acid and given materail is also solid.So base+acid to give salt to get its presence

Part2 Since salt is insoluble in water, so , it will not dissociate in to acid and base .SO HERE WE WILL CAN NEED BOTH HCL AND NAOH
