What is the concentration of hydronium ions in a solution given that the concentration of hydroxide ions is 2.31 × 10 -4 m?

 4.32 X

Explanation: Given concentration of hydroxide ions = 2.31 x

As we know that Kw ( ionic product of water) at 25 °C =

and Kw is the product of concentration of hydronium ions and hydroxide ions.

Thus,

Kw =

=   X 2.31 x

/ 2.31 x =

= 4.32 X

Thus, the concentration of hydronium ions in a solution = 4.32 X

answer: at room temperature (roughly 20 degrees c), you can dissolve 203.9 grams (or 200 grams) of sugar in 100 ml of water. as water temperature increases, the amount of sugar that will dissolve increases, up to about 500 grams of sugar in 100 ml water at 100 degrees c.

explanation:

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.
