Calculate the concentration of h3o⁺ in a solution that contains 6.25 × 10-9 m oh⁻ at 25°c. identify the solution as acidic, basic, or neutral. a) 6.38 × 10-9 m, basic b) 1.60 × 10-6 m, acidic c) 7.94 × 10-11 m, acidic d) 7.38 × 10-3 m, basic e) 4.92× 10-5 m, acidic

B) M, acidic

Explanation:

pH or pOH is the measure of acidity or alkalinity of a solution.

pH is calculated by taking negative logarithm of hydrogen ion concentration and pOH is calculated by taking negative logarithm of hydroxide ion concentration.

Acids have pH ranging from 1 to 6.9, bases have pH ranging from 7.1 to 14 and neutral solutions have pH equal to 7.

Given :

As pH is less than 7, the solution is acidic.

Thus solution is acidic and concentration of is

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )

the formula mass of a molecule or a compound is the sum of the atomic weights of the atoms in its empirical formula

(that's what i know about formula mass)
