  2. Piranha solution - Wikipedia

    en.wikipedia.org/wiki/Piranha_solution

    A closely related mixture, sometimes called "base piranha", is a 5:1:1 mixture of water, ammonia solution (NH 4 OH, or NH 3 (aq)), and 30% hydrogen peroxide. [ 2 ] [ 3 ] As hydrogen peroxide is less stable at high pH than under acidic conditions, NH 4 OH (pH c. 11.6) also accelerates its decomposition.

  3. pH - Wikipedia

    en.wikipedia.org/wiki/PH

    In such cases, the system can be treated as a mixture of the acid or base and water, which is an amphoteric substance. By accounting for the self-ionization of water, the true pH of the solution can be calculated. For example, a 5×10 −8 M solution of HCl would have a pH of 6.89 when treated as a mixture of HCl and water. The self-ionization ...

  4. Ammonia solution - Wikipedia

    en.wikipedia.org/wiki/Ammonia_solution

    In aqueous solution, ammonia deprotonates a small fraction of the water to give ammonium and hydroxide according to the following equilibrium: . NH 3 + H 2 O ⇌ NH + 4 + OH −.. In a 1 M ammonia solution, about 0.42% of the ammonia is converted to ammonium, equivalent to pH = 11.63 because [NH +

  5. Aqua regia - Wikipedia

    en.wikipedia.org/wiki/Aqua_regia

    Aqua regia (/ ˈ r eɪ ɡ i ə, ˈ r iː dʒ i ə /; from Latin, "regal water" or "royal water") is a mixture of nitric acid and hydrochloric acid, optimally in a molar ratio of 1:3. [ b ] Aqua regia is a fuming liquid.

  6. Neutralization (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Neutralization_(chemistry)

    The pH at the end-point depends mainly on the strength of the acid, pK a. The pH at the end-point is greater than 7 and increases with increasing concentration of the acid, T A, as seen in the figure. In a titration of a weak acid with a strong base the pH rises more steeply as the end-point is approached. At the end-point, the slope of the ...

  9. Mixing ratio - Wikipedia

    en.wikipedia.org/wiki/Mixing_Ratio

    The condition to get a partially ideal solution on mixing is that the volume of the resulting mixture V to equal double the volume V s of each solution mixed in equal volumes due to the additivity of volumes. The resulting volume can be found from the mass balance equation involving densities of the mixed and resulting solutions and equalising ...
