This dissociation occur because:
O had to bond with H due to the Hydrogen bonding rule, which will form OH~ (Hydroxide).
K is more attracted to Hydroxide than Cl, so it will depart Cl and bond with OH~.
that leaves a H and a Cl, which one has a positive charge and the other has a negative, so they will bond and form Hydrochloric Acid.
After the complete neutralization reaction occurs, excess hydroxide ion is left unreacted the hydroxide ion of the resulting solution, [OH-] is 0.02 M.
<h3>What is the concentration of the hydroxide ion, [OH-]?</h3>The hydroxide ion concentration is the amount in moles of hydroxide ion in a solution.
The hydroxide ion concentration is written as [OH-].
The equation of the reaction is given below:
1 mole of HBr reacts with 1 mole of KOH
Moles of HBr = 40 mL × 0.1 M = 4 mm moles
Moles of KOH = 60 mL × 0.1 M = 6 m moles
Moles of [OH-] = 6 - 4 = 2 m moles
Volume of solution = 100 mL
Thus, the concentration of the hydroxide ion, [OH-] is 0.02 M.
