Acid-Base Reactions Objectives Calculate the hydrogen ion and hydroxide ion concentrations in water Calculate pH values Explain why indicators change color Self Ionization of Water H2O H+ + OH- A reaction in water that produces ions. In pure water, the concentration of water molecules, [H2O...
dissolves mineral build-up from glass and tile, and removes the oxide residue from steel, brass, and bronze. The low pH gives it bactericidal activity. The acidity is used in baking to react with alkaline leavening agents. The acid-base reaction produces carbon dioxide gas bubbles that cause...
A large Ka value indicates a strong acid because it means the acid is largely dissociated into its ions. A large Ka value also means the formation of products in the reaction is favored. A small Ka value means little of the acid dissociates, so you have a weak acid. The Ka value for...

this target template might beRNAtranscribed from an induced gene of interest or an RNA present in biological tissue as a consequence of viral infection. The other template is a competitor added to each PCR reaction as a dilution series in an increasing and known amount. The two templates, ...
there is no evidence that sulfurous acid exists in solution, while the molecules of which has been detected in the gas phase, since the reaction is reversible and the acid readily decomposes back into the reactants. Sulfurous acid is not usually available in its acid form, but more commonly...
The reaction was then blocked by adding 10 mL 1× PBS into each tube, and solution was passed through a 40 μm cell strainer. The nuclei were centrifuged down at 500×g at 4 °C, resuspended in the resuspension buffer (10 mM pH = 7.5 Tris-HCl, 10 mM NaCl, 3 mM ...
