What is [H3O^+] if pOH =5.44 Is this solution acidic, basic or neutral? pH level: The pH level of a solution determines whether it is an acid or a base. pH levels at 7 indicate neutral solutions, ph Levels > 7 indicate bases, and pH levels < 7 indicate acids. T...
The concentration of hydronium ion in a solution of an acid in water is greater than 1.0 × 10−7 M at 25 °C. The concentration of hydroxide ion in a solution of a base in water is greater than 1.0 × 10−7 M at 25 °C. The concentration of H3O+ in a solution can be expr...
There are strong bases that are present in chemistry which is similar to a strong acid that can undergo complete (or 100%) dissociation. Examples of strong bases we have in chemistry are NaOH, LiOH, and KOH. Their behavior is kind of similar to salt...
The identification of the nature of the surface acid base pairs present on hydroxyapatites surface is a key point to rationalize their catalytic properties. To investigate the possible involvement of acidic protonated phosphate (POH) and/or of basic OH emerging from the channels, the spectroscopic ...

By the time PhN*H+ relaxes to the ground state, the solution is poised in acid-base disequilibrium. The transient deviation of the ground-state reactants from equilibrium is monitored through absorption changes of a pH indicator. Under conditions where the indicator is mostly protonated, pH pK...
