Answer:
The correct answer is option (e).
Step-by-step explanation:
Concentration of hydroxide ions
![[OH^-]= 5.5* 10^(-5) M](https://img.qammunity.org/2020/formulas/chemistry/college/cgmxyj62e1w4kh0dmrwd3oc6zkh6w6vxyd.png)
The pOH of the solution is defined as negative logarithm of hydroxide ions of in an aqueous solution.
- Higher the value of pOH more will be the acidic solution.
- Lower the value of pOH more will be the basic solution.
- At value equal to 7 the solution is said to be neutral.
![pOH=-\log[OH^-]](https://img.qammunity.org/2020/formulas/chemistry/high-school/n477c3o3xy8p6ug3ipfjqh9fd53hdrrjyq.png)
![pOH=-\log[5.5* 10^(-5) M]=4.259](https://img.qammunity.org/2020/formulas/chemistry/college/r9fjwvp6bdoksvkf84cl6uhbspu5mbnz8r.png)
pH +pOH = 14
pH = 14-pOH
pH=14 - 4.259 = 9.741
The pH of the solution is defined as negative logarithm of hydronium ions of in an aqueous solution.
- Higher the value of pH more will be the basic solution.
- Lower the value of pH more will be the acidic solution.
- At value equal to 7 the solution is said to be neutral.
![pH=-\log[H_3O^+]](https://img.qammunity.org/2020/formulas/chemistry/high-school/f390cegazdnm7uy3e4lyqajx4gquacwg62.png)
![9.741=-\log[H_3O^+]](https://img.qammunity.org/2020/formulas/chemistry/college/hel7z3oygwc5i2jgthtdyobyu994xjx1sv.png)
![[H_3O^+]=1.8* 10^(-10) M](https://img.qammunity.org/2020/formulas/chemistry/college/wnew3702iu6tpznk1xsl8v1vk3z8c88p8g.png)
The solution is basic as pH of the solution is 9.741.
