Answer:
is the hydrogen ion concentration.
0.0002773 M is the hydroxide ion concentration.
The solution has pH value more than 7 which means that it is base.
Step-by-step explanation:
The pH of the solution is defined as negative logarithm of hydrogen ions concentration in a solution. Lower the value of pH more acidic will the solution.
Mathematically written as:
![pH=-\log[H^+]](https://img.qammunity.org/2020/formulas/chemistry/middle-school/vz65x0ueuj8r8ibqa81zvsbzb2yaetlce4.png)
The pOH of the solution is defined as negative logarithm of hydroxide ions concentration in a solution. Lower the value of pOH more alkaline will the solution.
Mathematically written as:
![pOH=-\log[OH^-]](https://img.qammunity.org/2020/formulas/chemistry/high-school/n477c3o3xy8p6ug3ipfjqh9fd53hdrrjyq.png)
The sum of ph and pOH is equal to 14.
pH + pOH = 14
We have:
Solution with pOH = 3.557
The pH of the solution = 14 - pOH = 10.443
