Calculate the hydronium ion concentration in an aqueous solution with a ph of 9.85 at 25°c. calculate the hydronium ion concentration in an aqueous solution with a ph of 9.85 at 25°c. 1.4 × 10-10 m 4.2 × 10-10 m 7.1 × 10-5 m 6.5 × 10-5 m 8.7 × 10-10 m

Answer : The hydronium ion concentration in an aqueous solution is,  

Explanation :  Given,

pH = 9.85

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

Formula used :

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

Therefore, the hydronium ion concentration in an aqueous solution is,
