Bases - pH Values pH values for bases like sodium hydroxide, ammonia and more. Buffer Solutions Definitions, explanations and examples of how to make buffer solutions. Food and Foodstuff - pH Values pH in common food products - like apples, butter, wines and more. ...
Some indicators can't identify acids or bases, but can only tell you the approximate pH of an acid or a base. For example, methyl orange only works at an acidic pH. It would be the same color above a certain pH (acidic) and also at neutral and alkaline values....

How are acids and bases measured? What happens during an acid–base reaction? acid–base reaction, a type of chemical process typified by the exchange of one or more hydrogen ions, H+, between species that may be neutral (molecules, such as water, H2O; oracetic acid, CH3CO2H) or elect...
The pH indicator definition can be explained as a dye that shows a change in color when brought in contact with acids and bases. This tells us whether an acid or base is being tested, with respect to the change of color. Indicators are used in a titration to show the completion of an...
because adding water to a solution will not change the equilibrium constant. Ka and pKa relate to acids, while Kb and pKb deal with bases. Like pH andpOH, these values also account for hydrogen ion or proton concentration (for Ka and pKa) or hydroxide ion concentration (for Kb and pKb)...
All the three compounds become stronger bases upon photoexcitation, as reported in the literature in the case of the analogous 2-styrylpyridine and 2,6-DStP [14,15,16, 21]. On the contrary, the bis-protonated DAQP becomes a much stronger acid in the excited state in agreement with the ...
