Answer is: <span> 1.4 × 10-10 m
</span>pH = 9.85.
[H₃O⁺] = 10∧(-9.85).
[H₃O⁺] = 1.4·10⁻¹⁰ M.
pH (potential of hydrogen) is a numeric scale used to specify the acidity or basicity <span>an aqueous solution.
</span>If pH is greater than seven, solution is base and if pH is equal seven, solution is neutral and if pH of solution is less than seven, than is acidic.<span>

Answer : The hydronium ion concentration in an aqueous solution is,  1.41\times 10^{-10}M

Explanation :  Given,

pH = 9.85

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

Formula used :

pH=-\log [H_3O^+]

Now put the value of pH in this formula, we get:

9.85=-\log [H_3O^+]

[H_3O^+]=1.41\times 10^{-10}M

Therefore, the hydronium ion concentration in an aqueous solution is,  1.41\times 10^{-10}M
