If I have I have hydrogen-ion concentration of 2.3x10^-3, what is the hydroxide-ion concentration?

4.2 X moles/litre is the hydroxide ion concentration of the solution if hydrogen-ion concentration of 2.3x.

Explanation:

Data given:

hydrogen ion concentration = 2.3 X

Hydroxide ion concentration =?

first the pH of the solution is calculated by using the formula:

pH = - log[]

Putting the values in the equation,

pH = - [2.3 X ]

pH = 2.63

Now from the relation we will find the pOH of the solution:

14 = pOH + pH

14 - pH = pOH

14 - 2.63 = pOH

11.37 = pOH

now using the formula to calculate OH ions in the solution as:

pOH = - []

[] =

          = 4.2 X moles/litre is the hydroxide ion concentration of the solution.

58750.08068 is the answer i think

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
