WebJul 24, 2016 · pH = 13.30. Explanation: Barium hydroxide is a strong base for both stages of dissociation: Ba(OH)2(s) → Ba2+ +2OH− So the solution will have 0.20 M hydroxide ions. Now use the autodissociation product for water: [H+][OH−] = 1.0 ×10−14M [OH−] = 2.0 × 10−1M [H+] = 5.0 ×10−14M And then pH = −log10([H+] = 5.0 × 10−14) = 13.30. Answer link

Each one pH increase is 10x less hydrogen ions and 10x more hydroxide ion, so a pH of 10 is 10^3 = 1000x ...
WebpH and pOH. Adding an acid to water increases the H 3 O + ion concentration and decreases the OH-ion concentration. Adding a base does the opposite. Regardless of what is added to water, however, the product of the concentrations of these ions at equilibrium is always 1.0 x 10-14 at 25 o C. [H 3 O +][OH-] = 1.0 x 10-14. The table below lists pairs of H 3 O + and OH … WebLook again at the table and verify that for any pH that [H +] x [OH -] = 1 x 10 -14 . Acids An acid may be thought of as a molecule that splits apart (dissociates) in water yielding a hydrogen ion and a negative anion, symbolized as A - . HA H + + A - (6) A - is also referred to as the conjugate base of the acid HA.
WebMay 24, 2015 · 373. May 23, 2015. #2. This is an important trick that must be remembered for the real DAT. When the concentration of HCL is smaller than 1x10-7 you have to consider water! Water has a [H] of 1x10-7 and thus if you add [HCL] 1x10^-8 you actually have a combined [H] of 1.1x10^-7. the the negative log of this is just under 7 ===> 6.98.
