A solution with a hydrogen ion concentration of 1.00 x 10E-3 M would have what hydroxide ion concentration? a 1.00 x 10E3 M b 1.00 x...

Choose a Formula

The relationship between the concentration of hydrogen ions ( ) and hydroxide ions ( ) is given by the following formula:

    [ ][ ] = 1.0 x

The square brackets in the formula stand for "the concentration of"

1.0 x  is the ionization constant for water ( )

Solve for the Hydroxide Concentration

We can rearrange the above formula to isolate the hydroxide ion [ ]. To rearrange the formula, divide both sides of the formula by [ ]:

    [ ] = 1 x /[ ]

Now, we can plug in the given value for the [ ] and solve for [ ]:

   [ ] = 1 x /1 x  

                = 1 x  M

So, the answer would be b.
