Question: What will be the pH of a soft drink if hydrogen ion concentration in sample is \(1.20molL^{- 1}\)M?...

What will be the pH of a soft drink if hydrogen ion concentration in sample is 1.20molL−11.20molL^{- 1}M?

A

[X]=0.06molL−1,[Y]=0.12molL−1,[Z]=0.216molL−1\lbrack X\rbrack = 0.06molL^{- 1},\lbrack Y\rbrack = 0.12molL^{- 1}, \lbrack Z\rbrack = 0.216molL^{- 1}

B

N2(g)+O2(g)N_{2(g)} + O_{2(g)}

C

2NO(g),2NO_{(g)},

D

KcK_{c}

Answer

2NO(g),2NO_{(g)},

Explanation

Solution

: pH = - log [H+]\lbrack H^{+}\rbrack

=−log⁡(3.8×10−3)=2.42= - \log\left( 3.8 \times 10^{- 3} \right) = 2.42
