WebSep 5, 2016 · In order to calculate the pH of this solution, you need to know the concentration of hydronium cations. The dissociation of the acid will produce. HCl(aq) +H2O(l) → H3O(aq) + Cl− (aq) Here every mole of hydrochloric acid added to the solution will produce one mole of hydronium cations. In your case, you have. [HCl] = … WebThe pH scale is used to rank solutions in terms of acidity or basicity (alkalinity). Since the scale is based on pH values, it is logarithmic, meaning that a change of 1 pH unit corresponds to a ten-fold change in H ^+ + ion …
WebApr 8, 2013 · 1 Answer. comes in handy. Because your molarities and volumes of the acid and its conjugate base are equal, this indeed reduces to simply p H = − log ( 6.3 ⋅ 10 − 5). For (b), the volume of H C l added is required, as the concentration of the solution alone is not sufficient information. The standard practice is to assume that H C l ... WebApr 27, 2015 · As you may have noticed, your answer of 11.65 is counter-intuitive as it is higher than 7, meaning that dilute hydrochloric acid is somehow more BASIC than water. The key here is accounting for the $1.0 \times 10^{-7} M$ H+ ions, or $1.507 \times 10^{-5}$ moles of H+ ions for 150.7L, already present in the water due to self-ionization.
