What is the pH of barium cyanide? - Answers

http://www.cameochemicals.noaa.gov/chemical/2555 WebBecause the pH of Lithia water is 6.4 and the concentration of the other ions is large, the contribution of H + and OH-to the charge balance reaction can be neglected. In other cases, such as solutions having low ionic strength, it may be necessary to include these species in the calculation of electroneutrality. WebAcids are substances that dissociate into H+ ions when you dissolve them in water. They have a higher concentration of H+ ions than OH- ions and in the pH scale, they range between 1 or more than 1 but lesser than 7. They turn blue litmus red. Bases are usually oxides or hydroxides. They dissociate into OH- ions when you dissolve them in water. some prefer nettles characters
