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.

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. make up artist schule

WebpH =-log 1.5x10-6 M pH=5.82. If pH= 5.82 and pOH=14-pH pOH=14-5.82=8.18 [OH-]=10-p OH so ... Example D. If [OH-]= 8.1x10-4 M and pOH =-log [OH-] pOH =-log 8.1x10-4 M pOH =3.09 If pOH= 3.09 and pH=14-pOH pH=14-3.09=10.91 [H +]=10-pH so [H +]=10-10.91 [H +]= 1.2x10-11 M. Back to Acid Base Links.
