hydrogen ions are released
1 of 26
What are hydrogen ions?
protons
2 of 26
In aqueous solutions, what happens to Hydrogen ions?
They are surrounded by water molecules.
3 of 26
What is "hydration"
when water molecules surround protons to keep them in solution.

What are acids?
proton donors.
5 of 26
.......acids ionise completely when they dissolve in water.
strong

what are bases?
proton acceptors.
8 of 26
What is an alkali?
a soluble base

weak
12 of 26
What takes place when acids and alkalis react?
neutralisation
13 of 26
How can volumes of solutions that react exactly be found?
titration
14 of 26
What is the first step in this process?
measuring alkali into a conical flask
15 of 26
what's the second step in this process?
adding an indicator
16 of 26
what is the third step in this process?
adding acid from a burette
17 of 26
How is the volume of acid found?
the reading on the burette
18 of 26
How can you increase the reliability of this test?
repeat the experiment
19 of 26
How can you increase the distinctiveness of the end point in this process?
either of the above.
20 of 26
strong acid + strong alkali =
any
21 of 26
weak acid + strong alkali =
phenolphthalein
22 of 26
strong acid + weak alkali =
methyl orange
23 of 26
number of moles =
mass in grammes divided by formula mass
24 of 26
what is the equation for nitric acid?
HNO^3
25 of 26
How do you work out volume?
moles/concentration & divide the answer by 1000 to get dm3
