True
Hydronium(H3O+) ions, which are formed when Hydrogen(H+) ions combine with water molecules.
The bicarbonate ion, HCO3-.
All of the answers are correct.
Acids release hydrogen+ ions (H+) when dissolved in water
cellular metabolism under anaerobic conditions, leading to buildup of lactic acid
Aye mate
Any acid or base should do the trick.Any compound with excess hydrogen ions (H+) or excess hydroxide ions (OH-). Also, any compound that absorbs hydrogen ions (H+) or hydroxide ions (OH-).
True
Hydronium(H3O+) ions, which are formed when Hydrogen(H+) ions combine with water molecules.
No. Carbonic Acid releases hydrogen ins and lowers pH. Carbonates and bicarbonates, which can be derived from it, do bind hydrogen ions and lower pH.
Acidity is produced by an excess of hydrogen ions (actually to be completely correct an excess of pi-hydronium ions) in a water solution. So, yes.
The bicarbonate ion, HCO3-.
When excess of hydrogen or hydronium ions are present in the solution , the solution will have pH less than 0. Phenolphthalein possesses dark orange color to the solution having pH less than 0. Hence, phenolphthalein will possess dark orange color in the presence of excess of hydrogen or hydronium ions.
All of the answers are correct.
Acidic solutions contain very high concentrations of hydrogen ions. In an acidic solution, then, the concentration of hydrogen ions is greater than the concentration of hydroxide ions.
If it is in water (supposedly meant by questioneer), the pH value is below 7.0, so it is an acid solution: more H+ than OH-
