The ph of lemon juice is approximately 2.4. at this ph, the hydronium ion concentration is closest to which value? 1. 250 m 2. 4.00 × 10−3 m 3. 2.50 × 10−12 m 4. 5.62 × 10−4 m

Answer : The correct option is, (2)

Explanation:

pH : It is defined as the negative logarithm of hydrogen ion or hydronium ion concentration.

The mathematical expression is :

or,

Now we have to calculate the concentration.

Therefore, the concentration is,
