Term
| H2CO3(aq) can become two things |
|
Definition
weak acid:H30 + HCO3 & becomes H2O +
CO2 |
|
|
Term
|
Definition
| if an equilibrium is disturbed by changing conditions,the position of the equilibrium moves to counteract that change |
|
|
Term
| (both reactions are in competition. eg temp can make circumstances favorable for one reaction over another |
|
Definition
| 1.higher temp>gas less soluble(escapes)>reaction shifts to create/replace CO2...thereforeH2CO3 decomposes to create CO2(H2CO3> |
|
|
Term
|
Definition
| more CO2 remains to dissolve in sltn>reaction can shift to consume xtra CO2(*remember: when [CO2]increases in H2O>H2CO3 is formed and for more carbonic acid |
|
|
Term
| When CO2 increases in water |
|
Definition
| H2CO3 is formed to counteract increase(to maintain balance)*CO2 + H2O->H2CO3 and vice versa.. |
|
|
Term
| pH of blood must be maintained between |
|
Definition
| 7.35 and 7.45...6.8to 8.0...DEATH |

Term
| BUFFER is ALWAYS made up of |
|
Definition
| weak acid & it's conjugate base of that weak acid OR weak base & it's conjugate acid of that weak base |
|
|
Term
| Buffer problems will always be considered in terms of |
|
Definition
| How much OH- or H+ is added to buffer solution...and what will reaction be |
|
|
Term
| CO2 reacts with H20 to form H2CO3(aq)...Whats M @room temp of water saturated with CO2?is solubility greater? |
|
Definition
|
|
Term
|
Definition
| a weak acid which makes an OK base b/c neither will react w/each other (cancel each other out) |
|
|
Term
|
Definition
| a weak acid-H2CO3 and its conjugate base (HCO3)..where CB is acid minus an H and replaced with an Na or K (metal Ion) |
|
|
Term
| to make buffer solution step 1, 2 |
|
Definition
1.add CO2 +H20-> H2CO3(aq)con greater,2.now addNaHCO3(aq)->>
Na+(aq) +HCO3-(aq) |
|
|
Term
| whichever is CB, whichever is CA |
|
Definition
| will eat acid, will eat base |

Term
| Solution is a buffer sltn if pH change is |
|
Definition
| less than 1 when acid or base is added |
