Arrange the following in the order of increasing acidity. List
the most acidic last.
CH3OH
CH3CO2H
CH3CH2CH2CH3
If given a table of acids and their pKas, how do you determine
which acid is stronger, especially when the table does not have the
compounds that are above listed on the table?
Here is a chart of the table given.
HCl pKa= -7. CH3CO2H pKa= 4.8. H2O pKa= 15.7. CH3CH2OH pKa= 16.
CHCH pKa= 25. H2 pKa= 35. H2NH pKa= 38. CH2CH2...

b) Calculate the pH after the addition of 2.1, 5.25 and 9.49 mL
of the base.(Show your work in detail for one of the volumes.)
e)Calculate the pH after adding 5.00 mL of KOH past the
equivalence point
1. The three categories of the accounting equation are:
2. Companies need a way to organize their accounts so they use a
chart of accounts. Accounts starting
with 1 are usually Assets, 2 – Liabilities, 3 – Equity, 4 –
Revenues, and 5 – Expenses. The second
and third digits in account numbers indicate:
3. A chart of accounts and a ledger are similar in that they
both list the account names and account
numbers of the business. A ledger,...
