The concentration of hydrogen ton in a
sample of soft drink is 3.8 x 10 M. what
is its pH?
solution is given but I think that in soft drink there is an acid called carbonic acid ( H2CO3) whose bascity is 2
and the normality=n × molarity
= 2×3.8×10^_3
what do you think guys...
am I right or wrong..

Answer:
,pH is defined as - log10 of [H+]
ph = - log_{10} |h + |
So pH =
- log_{10} \times 3.8 \times 10^{ - 3}
= - ( - 3)log10 - \: log \: 3.8
As log 10 is 1 we get
= 3 - 0.5798
ph \: = 2.42

pH is defined as - log10 of [H+]
ph = - log_{10} |h + |
So pH =
- log_{10} \times 3.8 \times 10^{ - 3}
= - ( - 3)log10 - \: log \: 3.8
As log 10 is 1 we get
= 3 - 0.5798
ph : = 2.42
Explanation:
As pH is the negative of log of hydrogen ion concentration.
Mathematically, pH = -log [H^{+}]
It is given that concentration of hydrogen ion in the given sample is 3.8 \times 10^{-3} M. Therefore, calculate the pH of this sample as follows.
pH = -log [H^{+}]
= -log (3.8 \times 10^{-3})
= 2.42 .
Therefore, we can conclude that the pH of given sample of soft drink is 2.42.
