Hydrochloric ,acid,(HCl) and sulfuric ,acid, (,H 2SO 4,) are common examples of Arrhenius acids because, when they dissociate into their ions, they increase the amount of H+ in the solution: HCl → H+ (aq) + Cl− (aq),H 2SO 4, → H+ (aq) + HSO− ,4,(aq)Arrhenius defined a base as a substance that produces hydroxide (OH−) in aqueous solutions.

To platinize, prepare a solution of 1 g chloroplatinic ,acid,, ,H, 2 PtCl 6 ·6H 2 O, and 12 mg lead acetate in 100 mL distilled water. A more concentrated solution reduces the time required to platinize electrodes and may be used when time is a factor, e.g., when the cell constant is 1.0/cm or more.

How to optimize wastewater dosing - Filtration + Separation

Essentially, wastewater effluent flowing into the sewer system should be neither too acidic nor too basic (ideally completely neutral at pH 7), as this will help to prevent undesirable chemical reactions when the wastewater mixes with other effluent. pH neutralisation is even more important if the wastewater outlets directly into a lake or river, as changing the localised pH can harm wildlife and …
