The (oh) of a given solution =1.00x10-9m. what is this solution s poh?

9

Explanation:

Given parameters:

Concentration of OH⁻ [OH]= 1 x 10⁻⁹M

Solution:

To find the pOH of a solution can be found using the expression below:

                   pOH = -log₁₀[OH]

          [OH] = concentration of the hydroxyl ions

       pOH = -log₁₀(1 x 10⁻⁹) = - x -9 = 9

The soultion of pOH=9

Explanation:

We can determine the acidity or the basicity of the solution using the pOH value.

The solution is acidic if the pOH value ranges from 7.1 to 14

The solution is Basic if the pOH value ranges from 0 to 6.9  

The solution is neutral if the pOH value is 7.

pOH is defined as the negative logarithm of the Hydroxide ion concentration, that’s why the formula to find pOH is given by  

(Answer)

Please note :  

A Base is a substance which produces one or more hydroxyl ion or  hydroxide ion (OH-) in aqueous solution.

Examples

Please note:

(aq) stands for aqueous which means in the presence of water that is,water   acts as a solvent

So, on adding a base to the water increase in will take place and this will decrease the Hydrogen ion concentration  

Pure water contains

if the solution is acidic

if the solution is Basic

assuming that your periodic table has eighteen columns, you should highlight   the four elements in the third column from the left of the table.

neutral atoms of elements after calcium contain d electrons. the energy of d orbitals of a particular main shell lies between the energy of the s and p orbitals of the next main shell. for example, electrons in the have energy higher than those in the orbital while lower than those of the orbital.

by the aufbau principle, electrons fill orbitals one at a time, starting from those of the lowest energy. the orbital is therefore filled right after orbitals and before orbitals.  

potassium has electron configuration and calcium . the s orbital of a main shell holds a maximum of two electrons. the next element would thus have the electron configuration and satisfy the requirements.

a neutral atom of the element contains three electrons on top of the most recent noble gas element. it should thus be placed in the third column of the periodic table. both scandium and yttrium would satisfy the conditions. an aufbau diagram indicates that the 4f orbital is filled before the 5d. however, it appears that exceptions exists for both lanthanum and actinium. neutral atoms of the two d-block elements also demonstrate the and should be highlighted as well.
