1.41 × 10⁻¹⁰ MExplanation:We have a solution with a pH of 9.85 at 25 °C. We can calculate the concentration of H⁺ using the following expression.pH = -log [H⁺] [H⁺] = antilog -pH[H⁺] = antilog -9.85[H⁺] = 1.41 × 10⁻¹⁰ MH⁺ is usually associated with water molecules forming hydronium ions.H⁺ + H₂O → H₃O⁺ Then, the concentration of H₃O⁺ ions is 1.41 × 10⁻¹⁰ M.

Prof. Carlos Prohaska Jr. · Answer

Approximately . Explanation:The hydronium ion concentration of an aqueous solution can be found from its with the equation:.For this solution, . Hence,. Note that for this equation, the number of significant figures in should be the same as the number of decimal places in . For example, the of this question comes with only one decimal place. As a result, there would be only one significant figure in the obtained from the equation.

Jules Schiller · Answer

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

We have been given the pOH value, then we can calculate the pH value.pH + pOH = 14pOH = 9.85 pH = 14 - 9.85 = 4.15We can calculate the hydronium ion concentration using pH valuepH = -log [H₃O⁺][H₃O⁺] = antilog(-pH)we can calculate antilog of pH by writing it as 10^(-4.15)[H₃O⁺] = antilog (-4.15)[H₃O⁺] = 7.07 x 10⁻⁵ M
