WebTitrating a solution with an acid whose concentration is already known allows one to calculate the value of the solution's pH. In this instance, 75.0 mL of 0.200 M NH3 was used, and 0.500 M HNO3 was used to titrate it. Calculations may be made on the quantity of NH3 that is left behind after 19.0 mL of HNO3 has been added.

WebWhat is the pH of a 1.0 x 10^-10 M HNO3 solution? I tried writing the dissociation equation (HNO3 --> H+ + NO3-), and I got the concentration of H+ to be 1.0 x 10^-10 M, since it's 1:1. When I plug that into the pH = -log[H+] equation, I got that the pH would be 10. WebOct 18, 2024 · 25K views 2 years ago HNO3 is a strong acid, so every single HNO3 molecule breaks apart into an H (+1) ion and an NO3 (-1) ion. This means 0.1 mol/L of HNO3 yields 0.1 mol/L of H (+1) ions.... sims 4 sims 3 background
Whats the pH value of 10^-8 M HNO3? - ECHEMI
WebJan 6, 2024 · For example, [H +] = 10-6.5 will immediately give a pH value of 6.5.You get the same result if the [H +] ion concentration is written as 0.00000031623 M (or 3.1623 × 10-7 M).M is the number of moles of the substance per liter of solution. Check molarity formula using this calculator.. Note that the more hydrogen ions [H +] the acid provides, the lower … WebIn this case, we have ethylamine (C2H5NH2) as a weak base, and we want to prepare a buffer solution with a pH of 10.520, which means that the concentration of H+ ions should … WebNov 24, 2024 · [H3O+] = 3.5 ⋅ 10−3.M Now, the pH of the solution is simply a measure of the concentration of hydronium cations. pH = −log([H3O+]) −−−−−−−−−−−−−−−−−−−− Plug in … sims 4 sims 4 male child hair
