Neutralization Reaction
when an acid and a base react to form water and a salt, it involves the combination of H+ ions and OH-ions to form water.

Which type of reaction are all acid-base neutralization reactions? Explain your answer.
Acid-base neutralization reactions are double replacement reactions. The positive ions are exchanged between the acid and base reactants; the produces are a salt and water
What occurs at the end point of titration
At the endpoint of a titration the indicator changes color. Ideally, the end point is equal to the equivalence point, where the moleacid=molebase (point of neutralization)
Fill in the missing product in the following neutralization reaction. HNO3 + KOH → Answer + H2O
Fill in the missing product in the following neutralization reaction. HNO3 + KOH → KNO3 + H2O
Write the complete balanced equation for the following acid-base reactions.a. H2SO4(aq) + KOH (aq) →
H2SO4(aq) + 2KOH (aq) →2H2O (aq) + K2SO4 (aq)

How many moles of HCl are required to neutralize aqueous solutions of these bases?0.1 mol Ca(OH)2
So, for every mol of Ca(OH)2 we get 2 mol of OH-, so we need 2 mol H+ to neutralize 1 mol Ca(OH)2
titration
The process adding a known volume of a solution (with a known concentration) to another solution (with a known volume and unknown concentration)
What are the products of a reaction between an acid and a base?
The products of an acid-base reaction are a salt and water.
titrant or standard solution in titration is called
The solution with a known concentration
When a strong acid and a strong base react (in a ratio specified by the balanced equation, [H+]=[OH-]) what i sproduced
a neutral (pH = 7) solution is produced
Ideally, the end point is the same as
equivelance point or point of nutuizlatation
The end point
is the point at which the indicator just starts to change color (and does not lose its color immediately when mixed)
Remember neutralization is when the moles of acid =
moels of base
Molarity (M) =
mol/L.
nATURILIZATION Reaction
reaction of an acid with a bas, hydrogren ions and hydroxide ion to produce water usually carried out by titration

what is idicated when changes color
the end point of tittration
The equivalence point is reached when
the number of mole of acid equals the number of moles of base
When acid and bases are mixed (in the lab), the equivalence point is created what is this?
the number of mole of acid equals the number of moles of base
what happens to nueterilization with weak acids or bases?
they do not have a7 equivelance points
