Explanation:
Explanation:


The above two reactions xcan also be written in form of single chemcial equation:
![FeCl_3+K(SCN)\rightleftharpoons KCl+[Fe(SCN)]Cl_2(blood-red)](https://tex.z-dn.net/?f=FeCl_3%2BK%28SCN%29%5Crightleftharpoons%20KCl%2B%5BFe%28SCN%29%5DCl_2%28blood-red%29)
1. Color of ferric chloride solution is yellow. This is due to presence of ferric ions which have yellow color in their aqueous solutions.
2. KSCN has the colorless solution. This due to potassium ion forms colorless aqueous solution.
3. On mixing, KSCN with
we will get blood red color solution of
.
we will calculate pH of nitric acid of 0.1 M concentration. So, concentration of hydrogen ions in HNO3 is 0.1 M. And now by using this formula we will find pOH. So, from this we can say that pH of HNO3 is 1 and pOH of HNO3 is 13.
