2012年10月28日 · CO2 is an acid anhydride. It really is not a (Bronsted/Lowry) acid until it is added to water. Then it becomes carbonic acid (H2CO3). CO2 + H2O --> H2CO3. Then the carbonic acid can dissociate to make a proton (H+) and bicarbonate ion (HCO3 (1-)), newer nomenclature calls it the hydrogen carbonate ion, but it is the same thing. Since the bicarbonate ion is the product of the dissociation, it ...

2010年8月12日 · Carbonic acid is just unstable. It automatically degrades into H2O and CO2, which are just the lewis acid (CO2) and attacking base (H2O) forms of carbonic acid.

2010年5月24日 · CO2 is the biggest source of acid in the body because it binds to H20 in the blood and forms carbonic acid which then dissociates into H+ and HCO3-. If you keep this equation in mind it'll make sense why hypoventilation (build up of CO2) and hyperventilation (blow off too much CO2) produce respiratory acidosis and alkalosis respectively.

2013年7月31日 · Hi guys, I'm doing some in vitro fatty acids oxidation assay following the protocol by Sweeney 2005 (Diabetologia 48: 132–139). Basically I trap the radiolabelled CO2 with filter paper which was previously soaked in phenetylamine:methanol and then I count the activity of each piece fof filter pap...

2008年2月22日 · Can you use carbonic acid for electrolysis, and what would you get if you did? Would using carbon electrodes make this more interesting?

2009年7月20日 · How would this effect the purity of the acid product? How could you tell if your acid product was contaminated in this way? Use an equation to help explain this. 3. Why is CO2 generated in the sodium bicarbonate test. Explain the evolution of CO2 in the bicarbonate test using an equation. Also, why do we perform chemical tests?

2005年11月24日 · This is an acid base neutralisation reaction. The baking soda (aka sodium bicarbonate, NaHCO3) is the base and the vinegar (aka acetic acid, CH3COOH) is obviously the acid. The two react to form a salt, water, and carbon dioxide: NaHCO3 + CH3COOH ----> CH3COO-Na+ + H2O + CO2 The resulting solution will in fact be basic rather than acidic as the CH3COO- ion is a medium strength base.

2014年4月29日 · When a 1.25-gram sample of limestone CaCO3 was dissolved in hydrochloric acid, 0.44 gram of CO2 was generated.?

2003年3月25日 · The hydroxide anion reacts with acetic acid thus decreasing its concentration relative to the base; this is the only significant change. Thus account for the decreased concentration of acetic acid.

2010年1月23日 · Baking powder (rather than soda) contains an acid (classically cream of tartar, but others get used). On heating bicarbonates are converted to carbonates and CO2 and water.
