The following solution is suggested to handle the subject “Complete the Kw expression for the autoionization of water. Kw=1.00*10^-14“. Let’s keep an eye on the content below!
Question “Complete the Kw expression for the autoionization of water. Kw=1.00*10^-14”
Complete the Kw expression for the autoionization of water.
Kw=1.00*10^-14
Answer
Answer 1
H2O <=> H+ + OH-
Kw = [H+][OH -]
Answer 2
H2O (l) + H2O (l) <==> HTML3O+(aq), + OH
Answer 3
The autoionization of water is
2H2O(l)↽−−⇀H3O+(aq)+OH−(aq)
Recall that pure liquids are not included in the ?w
expression. The concentrations of the products are in the numerator of the expression, and the concentrations of the reactants are in the denominator. Therefore, the ?w
expression is
?w=[H3O+][OH−]
Conclusion
Above is the solution for “Complete the Kw expression for the autoionization of water. Kw=1.00*10^-14“. We hope that you find a good answer and gain the knowledge about this topic of science.
