| Question | Answer |
|---|---|
| Ph is a measure of ....... ion concentration in solution | hydrogen |
| Acids have a pH range of pH ...... nuetral is pH ........... and bases have a pH range of ......... | <7 7 >7 |
| a pH of 3 has ....... times the concentration of H+ ions something with a pH of 4 | 10 |
| a pH of 3 has ..... times the concentration of H+ ions as something with a pH of 5 | 100 |
| An indicator changes ..... to indicate a change in pH | colors |
| What colors does litmus paper turn in the presence of an acid or base? | A:red B: blue |
| 4 properties of an acid | sour, produces H+, ph <7, litmus red |
| 4 properties of a base | bitter, slippery, produces Oh-, ph >7, litmus blue |
| 3 Facts of Sulfuric acid | used in production of paper, petroleum refining and fertilizers |
| 3 Facts of Nitric Acid | used in production of explosives, fertilizers and stains proteins |
| 3 Facts of Hydrochloric acid | sold as muriastic acid, part of a gas juice, pickling of steel, purifying magnesium |
| 3 Facts of phosphoric acid | vinegar, plastics and pharmaceuticals |
| When acids react with bases in neutralization reactions, what two things are always formed | a salt and h20 |
| HBr | hydrobromic acid |
| HNO3 | nitic acid |
| HNO2 | nitrous acid |
| chlorus acid | HCI02 |
| Chloric acid | HCI03 |
| hydrofluoric acid | HF |
| What do acids and bases do according to the Arrhenius definition? | Acids: Produce h+ ions Bases: Produce OH- ions |
| What do acids and bases do according to the Bronsted-Lowry definition? | Acids: Donate h+ Bases: accept H+ |
| What do acids and bases do according to the Lewis Definition | Acids accept electron pairs and bases donates electron pairs |
| The idea of conjugate acids and bases is based on the........ definition of acids and bases | Bronsted-Lowry |
| The conjugate base/acid is the particle left over after an acid.. donates/accepts a proton | conjugate base donates |
| The conjugate base/acid is the particle left over after an acid.. donates/accepts a proton | acid accepts |
| What is a monoprotic acid? | donates one hydrogen |
| What is a polyprotic acid? | can donate more than one |
| HF mono or poly? | mono |
| H2S04 mono or poly? | poly |
| Define amphoeteric and list the most common amphoteric substances | can either donate or accept hydrogen ions ex: water |
| Which is stronger acid, HI with 60% ionization or h2S with 35% ionization | more ionization the more it dissociates so it is a strong acid |
| the process of using a specific volume of a solution with known concentration to react with a measures amount of solution of unknown concentration is called | titration |
