Ph of 20% hcl
WebWhat is Hydrochloric Acid? Hydrochloric Acid (HCL) is a clear, colourless, highly pungent solution of hydrogen chloride (HCl) in water. It comprises 0.2% - 0.5% of gastric juice. ... HCL maintains a pH in the stomach of approximately 2.0. It also dissolves food and kills microorganisms. WebTherefore, we can directly substitute HNO 3 concentration to pH calculation equation. pH = -log 10 [H + (aq)] We can write above equation for HNO 3 as below. pH = -log 10 [HNO 3 (aq)] pH of 0.1 mol dm-3 HNO 3 solution. pH = -log 10 [0.1] pH = 1; You can see, 0.1 mol dm-3 HNO 3 acid solution is strong acidic solution because pH value is well ...
