Literature guides Concept … chung hing chinese take out west babylonWebbpH is the negative logarithm of the hydrogen ion activity (roughly = the concentration - I will come back to this later). Thus (roughly) 0.1 molar HCl gives about -log (0.1) = 1. Because 0.1 = 10^ (-1). 0.01 M = pH 2, 0.001 M = pH 3, 0.0001 M = pH4. Thus 1 molar H+= pH 0. (1 M HCl would be a little bit higher because the ions are not 100% active.) detailing logo templatePhysical properties of hydrochloric acid, such as boiling and melting points, density, and pH, depend on the concentration or molarity of HCl in the aqueous solution.
