Calculate the pH for the weak acid/strong base titration between 50.0 mL of 0.100 M HCOOH(aq) (formic acid) and 0.200 M NaOH (titrant) at the listed volumes of added … WebAn acid can be defined as a substance that loses one or more H+ ions when dissolved in water. An H+ ion is a hydrogen atom that has lost a (n) and is therefore just a (n) . The H+ ion is not an isolated ion, but interacts strongly with H2O to produce the ion, which has the formula H3O+. Blank 1: electron Blank 2: proton, hydron, or cation WebSulfuric acid is the strongest acid on our list with a pK a value of –10, so HSO 4-is the weakest conjugate base. You can see that hydroxide ion is a stronger base than ammonia (NH 3), because ammonium (NH 4 +, pK a = 9.2) is a stronger acid than water (pK a = 14.00). The stronger the conjugate acid, the weaker the conjugate base. rough idle headlights dim
