Question

define pH calculate the pH of a soft drink if its hydrogen ion concentration is 10^-3also its nature​

Answer 1

pH = - log [H+]

pH = - log 10^-3

pH = -3 × - log 10

pH = 3 × 1

pH = 3.0

The nature of the soft drink is acidic.

Answer 2

$\huge {\red{\boxed{ \overline{ \underline{ \mid\mathfrak{An}{\mathrm{sw}{ \sf{er}} \colon\mid}}}}}}$

Given :

• Molar Concentration = 10-³ M

________________________

To Find :

• pH of Soft Drink

________________________

Solution :

Formula for pH is :

$\large \star {\boxed{\sf{pH \: = \: - \: \log [H^{+}]}}} \\ \\ \implies {\sf{pH \: = \: - \: \log \: 10^{-3}}} \\ \\ \implies {\sf{pH \: = -3 \: \times \: - \: \log \: 10}} \\ \\ \implies {\sf{pH \: = \: 3 \: \times \: 1}} \\ \\ \implies {\sf{pH \: = \: 3}}$

pH of Soft Drink is 3 means acidic in nature.
