Assume that for the pH 9.2 phenolphthalein sample, you used half as much phenolphthalein solution (i. e your sample is 9 ml buffer, 0.5 ml phenophthalein solution and 0.5 ml water). what should happen to the value of Kc you determine?

Explanation:

It is given that pH is equal to 9.2. So, we will calculate the value of as follows.

        pH =

Putting the given values into the above formula as follows.

    pH =

                  = 7.9

                       =

Since, the value of comes out to be positive. This means that there will occur an increase in the value of or .

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
