I DON'T get WHERE the excess bicarbonate ion comes from! Since carbonic acid dissolves to bicarbonate ion and H+, isn't already equal? The bicarbonates picks up the H+ coming from acids, but the H+ from the bicarbonate is still there! So the amount doesn't logically decreases at all!
It's about the amount of free protons (H+) in the blood. When metabolism produces additional acids ie. Lactic, then their is an increase in protons and pH should decrease. But, since H2CO3 is a weak acid, meaning it doesn't dissociate fully - so it's present both as an ion as well as a full acid; by adding more protons into the bloodstream than is normal, the equillibrium of the rection shifts to the left towards H2CO3, meaning the bicarbonate ion picks up the additional protons. It is then additionally changed into CO2 and water (beacause that reaction is linked) and CO2 is exhaled.
@gabrielstaniszewski8933 but then the acidity isn't from carbonic acid, but from lactic acid or whatever other acids are, so how is the expultion ofCO2 relevant? Again it's an equation, it's weak, so it doesn't dissolve alot, so the resulting protons and bicarbs are not a lot, bt it's still equal number,
The best simplified explanation of acid base buffer system ive ever seen
Thank youu
Most welcome! 🙏🏼
This is so precise and beautifully summarised. Grateful ❤️
Thank you for appreciating our work! 🥰❤️🙏🏼
So in water from where the buffers come
is this biochem
Best keep it up❤
Thanks! 🥰
I want to dilute lactic acid 80% to 1% lactic acid solution with distilled water, can i use sodium lactate or baking powder as buffer to maintain ph
Simplified❤

They are getting excreted in urine and stool this is why like in diarrhoea where you have metabolic acidosis due to Hco3 loss
bicarbonate is in excess because kidneys excrete more hydrogen ions relative to the the lungs 'excretion of co2
Lots of love ❤
Cooool ❤
Always fantastic❤
Thank you so much! 😀
you lost me in the section about cell pH :|
