酸碱平衡紊乱(Disturbance of acid-base balance)依据是Henderson-Hasselbalch方程原理:酸血症动脉血pH低于正常范围(低于7.36)。碱血症动脉血pH高于正常范围(高于7.44)。酸中毒是一种倾向于降低细胞外液pH值的过程(氢离子浓度增加)。这种现象的原因可能是血清H...
a pH of 7 is neutral, and a high pH value indicates alkalinity. The pH value can tell you whether you're dealing with anacid or a base, but it offers limited value indicating the truestrengthof the acid. The
Acid-Base Diagrams:Many diagrams have been devised to represent the relationship between arterial PCO2and pH. The best known is probably the Siggaard-Andersen Acid-Base Diagram1(S-A Diagram) shown here with typical zones. However, the axes for the PCO2and [H+] concentrations are logarithmic, t...
The Overview of Acid-Base Balance Respiratory:We breath to eliminate CO2.When breathing is inadequate carbon dioxide level rises. The extra CO2molecules combine with water to formcarbonic(respiratory) acid which contributes to an acid pH. Thetreatment, if all else fails, is to ventilate the patie...
pH range vs. color change for acid and base indicators - together with pKa and structures of the indicators.
在AP化学acid-basetitration(酸碱互滴)部分,ICE表格与pH=pKa+lg([A-]/[HA])都能求出氢离子浓度.但什么时候用第一个,什么时候用第二个?还是两个在相同题目中都可求出同样的答案?... 在AP化学acid-base titration(酸碱互滴)部分,ICE表格与pH=pKa+lg([A-]/[HA])都能求出氢离子浓度.但什么时候用第一...
Common Acid-Base Indicators Several acid-base indicators are listed below, some more than once if they can be used over multiple pH ranges. The quantity of indicator inaqueous(aq.) or alcohol (alc.) solution is specified. Tried-and-true indicators include thymol blue, tropeolin OO, methyl ...
We propose explicit and implicit approaches for the teaching of acid-base chemistry based on research into the history and nature of science (NoS). To supp
Acid–base homeostasis The organs involved in the maintenance ofacid base balanceare the lungs and kidneys, as well as a complex system of buffers (buffers). The interaction and proper function of these mentioned elements is required to maintain the arterial pH in optimal ranges (7.35–7.45). ...
High Altitude Diagram. Enter the Altitude and PCO2Units. For the selected High Altitude the Interactive Diagram provides the blood’s acidity (pH), the respiratory component (PCO2), metabolic component (Base Excess) and a text description. It is based on theSea Level Diagrambut instead of a ...
