the ph of lemon juice at 298 k is found to be 2.32. what is the concentration of $h_3o^+$ ions in the solution? use $h_3o^+=10^{-ph}$. 1.05×10⁻³ m 4.79×10⁻³ m 2.09×10² m 9.55×10² m

the ph of lemon juice at 298 k is found to be 2.32. what is the concentration of $h_3o^+$ ions in the solution? use $h_3o^+=10^{-ph}$. 1.05×10⁻³ m 4.79×10⁻³ m 2.09×10² m 9.55×10² m

Answer

Explanation:

Step1: Identify the formula

We use the formula $[H_3O^+]=10^{-pH}$.

Step2: Substitute the pH value

Given $pH = 2.32$, so $[H_3O^+]=10^{- 2.32}$.

Step3: Calculate the result

$10^{-2.32}\approx4.79\times 10^{-3}\text{ M}$.

Answer:

$4.79\times 10^{-3}\text{ M}$
