1.40 M NaOH

How many moles of HCl are required to neutralize aqueous solutions of these bases?a. 2 mol NH3

2 mol acid (H+

What is the molarity of the sodium hydroxide is 20.00 mL of the solution is neutralized by 17.4 of 1.00 M H3PO4?

2.61 M NaOH

Write the complete balanced equation for the following acid-base reactions.b. H3PO4(aq) + Ca(OH)2(aq)

2H3PO4(aq) + 3Ca(OH)2(aq) →6H2O(aq) + Ca3(PO4)2(aq)

Write the complete balanced equation for the following acid-base reactions.a HNO3(aq) + Mg(OH)2(aq)

2HNO3(aq) + Mg(OH)2(aq) →2H2O(aq) + Mg(NO3)2(aq)

How many milliliter of 0.45 M HCl will neutralize 25.0 mLof 1.00 M KOH?

56 HCI

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.

How many moles of sodium hydroxide are needed to neutralize 0.20 mol of nitric acid?

𝟎.𝟐𝐦𝐨𝐥𝐍𝐚𝐎𝐇

How many moles of potassium hydroxide are needed to completely neutralize 1.56 mol of phosphoric acid?

𝟒.𝟔𝟖𝐦𝐨𝐥𝐊𝐎𝐇

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
