No, when ascending, you would weigh more, and when you descend, you weigh less.
This is due to the difference in the effect of gravity.
Answer: The correct answer is Option a and d.
Explanation: Both the salts are ionic in nature because when dissolved in water, they dissociate into their respective ions.
Ionic compounds are held together by ionic bond. They are neutral compounds as both positive and negative charges neutralize each other. These compounds are also good conductors of electricity because of the presence of ions.
As both the salts have different molecular formula, both of them will have different crystal lattice system and hence, different crystal lattice energy.
From the above information, the correct options are option a and option d.
Explanation:
The given data is as follows.
= 0.042 M, for
According to the given situation acts as a base.The reaction equation will be as follows.
Relation between and are as follows.
=
=
Also,
Let us take = x
So,
x =
=
pOH = - log
= - log ()
= 4.99
As it is known that pH + pOH = 14
so, pH + 4.99 = 14
pH = 9.01
Thus, we can conclude that pH of the solution is 9.01.
