Graph for the conductometric titration between a weak acid and a srong base?
Weak Acid with a Strong Base, e.g. acetic acid with NaOH: Initially the conductance is low due to the feeble ionization of acetic acid. On the addition of base, there is decrease in conductance not only due to the replacement of H+ by Na+ but also suppresses the dissociation of acetic acid due to common ion acetate. But very soon, the conductance increases on adding NaOH as NaOH neutralizes the un-dissociated CH3COOH to CH3COONa which is the strong electrolyte. This increase in conductance continues raise up to the equivalence point. The graph near the equivalence point is curved due the hydrolysis of salt CH3COONa. Beyond the equivalence point, conductance increases more rapidly with the addition of NaOH due to the highly conducting OH− ions
A 0.361 molar solution of the weak acid HA with a pKa of 4.039 is titrated with a 0.163 molar solution of NaOH. What is the pH of the solution at the equivalence point of this titration?
At the equivalence point of the titration, all the weak acid HA has been neutralized by the strong base NaOH. This results in the formation of the conjugate base A-. The pH at the equivalence point of this titration would be determined by the salt formed by the reaction of the weak acid and strong base, and can be calculated using the Henderson-Hasselbalch equation.
Why only phenol dissolve in aqueous NaOH?
Phenol is not dissolved in a sodium hydroxide solution; having the characteristics of a weak acid phenol react with NaOH.
Is sodium hydroxide same as sodium phosphate?
No. Sodium hydroxide is NaOH; it is a strong base often used in drain cleaner. Sodium phosphate is Na3PO4; it is a weak base with a number of applications in cleaning and in food.
Is air pressure weak or strong at earths surface?
weak and strong,it depends
What is a strong acid NaOH HF NH3 HCl?
HCl is a strong acid, while NaOH, HF, and NH3 are not strong acids. NaOH is a strong base, HF is a weak acid, and NH3 is a weak base.
Can bases be strong or weak?
Yes. There are strong bases such as sodium hydroxide (NaOH) and weak bases such as ammonia (NH3)
Is NaF and NaOH a buffer?
No, NaF and NaOH do not form a buffer solution together as a buffer solution requires a weak acid and its conjugate base, or a weak base and its conjugate acid. NaF is the salt of a weak acid (hydrofluoric acid) and a strong base (NaOH), so it does not act as a buffer. NaOH is a strong base and cannot act as a buffer solution by itself.
Which pair consists of a weak acid and a strong base?
Acetic acid (CH3COOH) is a weak acid and sodium hydroxide (NaOH) is a strong base.
Is CH3NH3 a strong acid or base?
NH3 is a weak base, but H2CO3 ( carbonic acid ) is not a strong acid. It is a weak acid.
Is NaOH and NaCl a buffer system?
No, NaOH and NaCl do not form a buffer system. A buffer system consists of a weak acid and its conjugate base, or a weak base and its conjugate acid, to help maintain a stable pH. NaOH is a strong base and NaCl is a salt, so they do not act as a buffer system together.
Which is stronger NaOH or NH3?
Sodium hydroxide (NaOH) is typically stronger than ammonia (NH3) in terms of its basicity. NaOH is a strong base that dissociates completely in water to produce hydroxide ions, whereas NH3 is a weak base that only partially dissociates in water. This makes NaOH more effective in neutralizing acids and increasing the pH of a solution.
What effect does adding a small amount of NaOH to a buffer have on the pH?
Adding a small amount of NaOH to a buffer solution will increase the pH of the solution. This is because NaOH is a strong base that will react with the weak acid in the buffer, causing the pH to rise.
What are strong bases nh3 naoh baoh2 and hf?
NaOH is a strong base because it dissociates completely in water to produce hydroxide ions. NH3 is a weak base because it only partially ionizes in water. Ba(OH)2 is a strong base because it dissociates completely to produce hydroxide ions. HF is a weak base because it only partially ionizes in water.
Why alcohols do not react with NaOH?
Alcohols do not typically react with NaOH (sodium hydroxide) because alcohols are weak acids and NaOH is a strong base. The reaction between alcohols and NaOH would result in deprotonation of the alcohol, forming an alkoxide ion. However, this reaction is generally slow and inefficient due to the weak acidic nature of alcohols. Additionally, alcohols are poor nucleophiles, further hindering their reactivity with NaOH.
Why sodium carbonate is alkaline in nature?
Sodium carbonate is the product of the neutralization reaction between a strong base (NaOH) and a weak acid (H2CO3).
Which of the following is a weak base NH3 KOH LiOH or NaOH?
Ammonia solution is a weak base.
