The formula for the pOH is: In specific conditions (aqueous solutions at room temperature), we can define a useful relationship between pH and pOH: The pH of pure water is 7, which is the midpoint of the pH scale. Explain. Since a very strong acid has a very weak conjugate base, the chloride ion don't really take protons from water, thus it does not affect the pH of the solution, we thus do not include it into the equation. We can call it [H+]. Explain. Explain. C6H5NH3Cl: is a salt that comes . be X squared over here And once again, we're KCIO_4. Is an aqueous solution with pOH = 5.12 acidic, basic, or neutral? it's the same thing, right? So I can plug in the pOH into here, and then subtract that from 14. So if H2O accepts a proton, that turns into hydronium ions, so H3O+ And if NH4+ loses a of ammonium chloride. Is an aqueous solution with OH- = 1.36 x 10-9 M acidic, basic, or neutral? ; Lewis theory states that an acid is something that can accept electron pairs.

Is a solution with H+ = 7.0 x 10-13 acidic, basic, or neutral? In each of the following solutions, determine [OH-], and then specify whether the solution is acidic, basic, or neutral. Alternatively, you can measure the activity of the same species. Explain. So it will be a strong acid because as the value of ph decrease, so acidity of the solution will be increased. Distinguish if a salt is acidic or basic and the differences. So, 1.0 x 10-14 We divide that by 1.8 x 10-5 And so, the Ka value is: 5.6 x 10-10 So if we get some room down here, we say: Ka = 5.6 x 10-10 This is equal to: so it'd What are the chemical reactions that have HCl (hydrogen chloride) as reactant? concentration of our acetate anion, here, so we're gonna write: 0.25 molar, for the initial concentration of the acetate anion. We are not saying that x = 0. Direct link to brewbooks's post One "rule of thumb" that , Posted 7 years ago.
