The answer would be heterogeneous
Answer : The correct option is, (C) 1.7
Explanation :
First we have to calculate the moles of
and
.


The balanced chemical reaction will be:

0.01 mole of
dissociate to give 0.01 mole of
ion and 0.02 mole of
ion
and
0.03 mole of
dissociate to give 0.03 mole of
ion and 0.03 mole of
ion
That means,
0.02 moles of
ion neutralize by 0.02 moles of
ion.
The excess moles of
ion = 0.03 - 0.02 = 0.01 mole
Total volume of solution = 100 + 300 = 400 ml = 0.4 L
Now we have to calculate the concentration of
ion.


Now we have to calculate the pH of the solution.
![pH=-\log [H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%20%5BH%5E%2B%5D)


Therefore, the pH of the solution is, 1.7
The Avogadro's number determines how many items make up a particular unit, such that 1 mole of a substance contains 6.022 × 10^23 items.
These items may be particles such as molecules, atoms, ions , etc
Therefore, 1 mole of anything has 6.022×10^23 items.
This number is called the Avogadro's constant and applies to all substances, and is normally used by researchers and scientists to determine the number of moles of elements and compounds.
