The hydrogen ion concentration of 10-8m
WebThe hydrogen ion concentration of a 10 -8 M HCL aqueous solution at 298 K (K w = 10 -14) is: One mole of H2O and one mole of CO are taken in a 10 L vessel and heated to 725K. At … WebJun 11, 2024 · The pH scale ranges from 0 to 14. Values less than 7 indicate the acidity range and those greater than 7 indicate alkalinity or basicity. Value 7 is considered neutral. In this case, the concentration of the hydrogen ion is: [H⁺]=3.16*10⁻⁸ M Replacing in the definition of pH: pH= - log (3.16*10⁻⁸) pH= 7.50 The pH of the solution is 7.5

WebJan 30, 2024 · At very high concentrations (10 M hydrochloric acid or sodium hydroxide, for example,) a significant fraction of the ions will be associated into neutral pairs such as H + Cl –, thus reducing the concentration of “available” ions to a smaller value which we will call the effective concentration. WebAssume that acid rain has lowered the pH of a particular lake to pH 4.0. What is the hydroxide ion concentration of this lake? this question is looking for the concentration of OH- (Hydroxide) the H+ balance is 10^-4 so the OH- must add up to 14. So the concentration would be 10^-10 : As the pH lowers on the scale: the hydrogen levels (H+) go down.
