Sketch a graph for a titraton of a weak acid(burette) against 25cm^3 of strong base (conical flask). Assume that both have a concentration of 0.5M. Label axis please!

Expert Solution

Let the strong base be NaOH

So we have 25 ml of 0.5 M NaOH in conical flask

titration with 0.5 M of CH3COOH (weak acid) in burette

pKa of CH3COOH = 4.75

Let us calculate few data points for graph

CH3COOH (ml) pH

0 13.70

1 13.66

5 13.52

12.5 13.22

25 9.08 (equivalence point)

28 5.67

30 5.45

50 4.75 (half equivalence point)

75 4.45

100 4.27

What is the difference between a strong acid and a weak acid and a strong base and a weak base?

The reaction of the weak acid HCNHCN with the strong base KOHKOH is

The reaction of the weak acid HCNHCN with the strong base KOHKOH isHCN(aq)+KOH(aq)⟶HOH(l)+KCN(aq)HCN(aq)+KOH(aq)⟶HOH(l)+KCN(aq)To compute the pH of the resulting solution if 61 mL61 mL of 0.49 M0.49 M HCNHCN is mixed with 4.0×101 mL4.0×101 mL of 0.32 KOH0.32 KOH we need to start with the stoichiometry. Let's do just the stoich in steps:What are the moles of the pH active product after reaction? (remember the spectator ion is not pH active)

Weak base/ Strong acid titration curve question. 1) In the titration of .0400 M weak base B of 50 ml with .100 M HCl. What is the solution pH before any HCl is added? 2) In the titration of .0400 M weak base B of 50 ml with .100 M HCl. What is the solution pH after 10 ml HCl is added? 3) In the titration of .0400 M weak base B of 50 ml with .100 M HCl. What...

A weak acid is titrated with a strong base and the pH is measured at each interval. It the equivalence point is reached when 30 mL of the base has been added, describe how the pKa of the acid can be determined.

Consider a monoprotic weak acid (HA) that is titrated with a strong base. What is the relationship between the strength of the weak acid and the pH of the solution at the equivalence point? There is no relationship between the strength of the acid and the pH at the equivalence point. The pH at the equivalence point is always 7 in an acid base titration. The weaker the acid, the higher the pH at the equivalence point. The stronger the...

When a strong acid is neutralized by a weak base is the neutralization complete? Write the neutralization reaction for HClO4 and NH3. What is the value of Kn (equilibrium constant for neutralization)? (Kb(NH3)=1.810‒5) If stoichiometric amounts of acid and base are reacted will the resulting solution be acidic, basic or neutral?

Consider the titration of a weak base (B- ) with a strong acid (HCl). Draw (this can be hand drawn) a pH (not pOH) vs mL HCl graph (it will not look the same as the one in question #13; if you start with a weak base, will the pH be low or high? As H+ is added, will the pH increase or decrease?). Label the titration curve with letters A-E, and describe the relative quantities of the dissociated base...
