---|---|---|---|---|---|
Acid | proton donor. Has hydrogen (H+) or hydronium (H3O+) as the only positive ion in a solution
🗑
|
||||
Base | proton acceptor. Has hydroxide (OH-) as the only negative ion in solution.
🗑
|
||||
Ternary acids | Acid containing an ion from table E. It ends with "ic," or "ous."
🗑
|
||||
Acids on the pH scale | pH lower than 7. The lower you go, the stronger the acid. Each number is a 10x change in [H+]. Strong acids have [H+] is greater than [OH-]
🗑
|
||||
Bases on the pH scale | pH higher than 7. The higher you go, the stronger the base is. Strong bases have [OH-] is greater than [H+]
🗑
|
||||
Compare a pH 4 to pH of 6 | pH 4 is 100x more acidic or 100x less basic. PH 4 has 100x more [H+]
🗑
|
||||
Amphiprotic (amphoteric). PH’s around neutral so this substance can act as acid or base, depending on what it’s combined with. | PH’s around neutral so this substance can act as acid or base, depending on what it’s combined with.
🗑
|
||||
Neutralization | acid + base makes salt + water. pH approaches neutral.
🗑
|
||||
Electrolysis of salts | salt + water makes acid + base. If acid and base produced are both strong it will be neutral; If acid is stronger, pH will still be acidic. If base is stronger will be basic.
🗑
|
||||
Indicators | chemicals on table M that tell us the pH.
🗑
|
||||
Binary acids | Acid containing H+ and just one other element. Name starts with "hydro" and ends in "ic."
🗑
|
||||
Buffer | A chemical that resists changes in pH by neutralizing small amounts of added acid or base, keeping the pH of the solution relatively stable
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
