A bottle of soda has a PH of 3.
BaLLatris [955]

Answer:

The new pH of the solution = 6

Explanation:

Given

pH of bottle of Soda is 3

As we know that

pH = -log [H+]

We will derive the hydrogen ion concentration when pH is 3

3 = - log [H+]

Taking anti-log on both the sides, we get -

H+ ion is equal to 10^{-3}

When the hydronuim ion concentration reduces by \frac{1}{1000} of the original concentration, the new hydrogen ion concentration becomes

\frac{1}{1000000} = 10^{-6}

The new pH is

= - log [ 10^{-6}]\\= 6
