The reaction of the strong acid HCl with the weak base CH_3NH_2 is: HCl(aq) + CH_3NH_2(aq) rightarrow CH_3NH_3^+ (aq) + Cl^- (aq) To compute the pH of the resulting solution if 15mL of 0.31 M acid is mixed with 58mL of 0.90M base we need to start with the stoichiometry. Let's do the stoich in steps: How many moles of acid? How many moles of base? What is the limiting reactant? How many moles of the excess reagent after reaction?...
Describe how you expect the pH of your weak acid solution to change when strong base is slowly added to it. When making this description, assume you have a monoprotic acid. Comment on how much the pH changes at the beginning of the titration, when about half the acid has been titrated, and when nearly all the acid has been titrated. Use the terms half-equivalence point and equivalence point in this discussion. How would the titration curve of a diprotic...
4. Acetic acid is a weak acid and sodium hydroxide is a strong base, would you expect the equivalence point for this titration to be above pH 7, at pH 7, or below pH 7? Explain why this is the case. 5. Figure 3 shows the intermolecular forces present in 1-octanol. Identify and label these forces. Figure 3. 6. Sketch a diagram showing the intermolecular forces between acetic acid and water. 7. Sketch a diagram showing the intermolecular forces between...
This reaction is classified as: Strong Acid + Strong Base, Weak Acid + Strong Base, Strong Acid + Weak Base, Weak Acid + Weak Base. The extent of this reaction is: Below 50%, 50%, Above 50%, 100% When 35.0 mL of 0.300 M perchloric acid and 35.0 mL of 0.150 M barium hypochlorite are combined, the pH of the resulting solution will be greater than, equal to, less than seven. Write the balanced NET IONIC equation for the reaction that...
