När jag läser i kemi 2 boken så står det att HCO3- jonen i basisk lösning fungerar som en syra där denna reaktion sker: HCO3- + H2O → CO3 2- + H3O+ Det står att anledningen är att OH- tar en proton från HCO3- och jämviktsläget förskjuts åt höger.

Bicarbonate ion – Bicarbonate ion (HCO3-) is a normal constituent of the blood. Bicarbonate is naturally produced by the reaction of carbon dioxide (CO2) with water (H2O) to produce carbonic acid (H2CO3), which dissociates to a bicarbonate ion and a proton (H+). Acid/base metabolism in the body is regulated by this chemical equation:

Many bicarbonates are soluble in water at standard temperature and pressure ; in particular, sodium bicarbonate contributes to total dissolved solids , a common parameter for assessing water quality . 2020-04-14 · HCO3- (known as bicarbonate) is the conjugate base of H2CO3, a weak acid, and the conjugate acid of the carbonate ion. HCO3- acts as a base when mixed with a compound that is more acidic than itself (larger Ka) and as an acid when mixed with a compound that is more basic than itself (smaller Ka). Bicarbonate ion – Bicarbonate ion (HCO3-) is a normal constituent of the blood.

To accomplish this, acid (H ions) is secreted from cell to lumen across the apical membrane, and base generated within the cell exits into the interstitium across the basolateral membrane. HCO 3 + H----H 2 CO 3 ---H 2 O + CO 2 Och CO 2 nyttjas sen av algerna, dvs: för att algerna skall kunna nyttja HCO 3 så dras det bort en vätejon också. Då får vi alltså dels en förlust av en HCO 3 jon men också en förlust av en H-jon, dvs alkaliniteten ändras inte! Jag står således fast vid detta;-) • pH = - log {H+} • The pH of seawater varies only between about 7.5 and 8.4 (i.e., slightly alkaline) • Over geological time, pH is thought to be controlled by water/mineral equilibria • Over shorter time scales (104 to 105 yrs) the CO 2 system (and its shifting equilibria) regulates seawater pH CO 2(aq) + H 2O ↔ HCO 3-+ H+ H 2 CO 3 (aq) + H 2 O(l) ⇌ HCO 3 – (aq) + H 3 O + (aq) HCO 3 – (aq) + H 2 O(l) ⇌ CO 3 2– (aq) + H 3 O + (aq) According to the equations above, what is the conjugate base of HCO 3 –? a) H 2 CO 3 (aq) b) H 2 O(l) c) H 3 O + (aq) d) CO 3 2– (aq) 2012-06-03 · NaHCO3 + H + → Na + + H2O + CO2. here: Sodium bicarbonate has broke down into H2O and CO2. And we know that H2O and CO2 are common product & they are usually considered as 'bi-product' Therefore the above reaction is a decomposition reaction.
