Solve an equilibrium problem (using an ICE table) to calculate the pH of each of the following solutions. 1) .12 M HF pH = ? 2) a mixture that is 0.12 M HF in and 0.12M in NaF. pH =?
Terminal alkynes are acidic compounds, with pKa values around 25. That means they are about: a. one million times more acidic than water b. one billion times more acidic than water c. one billion times less acidic than water d. one thousand times ..
Balnace the following half reactions in an acidic solution a) MnO4 -(aq)---- MnO2(s) b) IO2- (aq)----Io4-(aq) based on (a) and (b) above, write balanced redox eqautions of (A) in an acidic solution MnO4-(aq) + IO3_(aq)----MnO2(s) + IO4- (aq) (A)
Most of the solid did not dissolve because the Ksp of ferric hydroxide is very small at 3 x 10^-39. However, when a certain amount of strong acid was added, the entire amount of solid dissolved. Determine the pH of the solution at that point that ..
In an acid base titration a 25mL portion of a solution containing sulfuric acid (H2SO4) was titrated with a 0.200M NaOH(aq). write the chemical equation for this particular titration
The equilibrium constant KC for the reaction 2H2(g) + CO(g) ? CH3OH(g) is 135 at a certain temperature. If there are 5.23 ? 10?2 moles of H2 and 3.73 ? 10?
