it is an acidic salt due to NH4+ ions being weak acid (pKa=9.2)
React aniline with HCl/NaNO2 (diazotisation) followed by reaction with KOH to give phenol. Nitration of phenol with fuming nitric acid gives picric acid (or trinitrophenol).
In the presence of sodium nitrite and hydrochloric acid, sulfanilc acid form a diazonium salt. This salt react with and is an indicator for thyrosine, histidine.
In a Brønsted-Lowry acid-base reaction, an acid donates a proton (H+) to a base, which accepts the proton. This results in the formation of a conjugate base from the acid and a conjugate acid from the base. The overall reaction involves the transfer of a proton from the acid to the base.
sodium (Na), nitrogen (N), and two oxygenatoms (O)
In a Brønsted-Lowry acid-base reaction, an acid donates a proton (H+) to a base, which accepts the proton. This transfer of protons characterizes the reaction, distinguishing it from other acid-base theories. As a result, the acid converts into its conjugate base, while the base becomes its conjugate acid. This framework highlights the dynamic nature of acid-base interactions in various chemical reactions.
A 0.1M solution of NaNO2 is acidic. Sodium nitrite (NaNO2) is a salt composed of a weak acid (nitrous acid) and a strong base (sodium hydroxide). The nitrite ion hydrolyzes in water to produce nitrous acid and hydroxide ions, which makes the solution acidic.
NaNO2 is a basic salt because it is formed from a strong base (NaOH) and a weak acid (HNO2). This makes the resulting salt slightly alkaline in aqueous solutions.
No.Since,sodium nitrite(NaNO2)is a salt of strong base and weak acid,in water solution it will leave more amount of [OH-] ions.Hence, solution will be basic.Therefore,NaNO2 is base not an acid.
NaHCl + HNO3 --> H2 + NaNO2 + ClO
HNO2 + NaOH -->NaNO2 + H2O
Formula: NaNO2
To calculate the pH of the solution, you need to consider the dissociation of both acids. Nitrous acid (HNO2) is a weak acid, while sodium nitrite (NaNO2) is a salt of a weak acid. Use the given concentrations to calculate the initial concentration of H+ ions from HNO2, then consider the effect of the NaNO2 on the pH by reacting with any excess H+ ions. Finally, calculate the pH using the equilibrium concentrations of the resulting species.
React aniline with HCl/NaNO2 (diazotisation) followed by reaction with KOH to give phenol. Nitration of phenol with fuming nitric acid gives picric acid (or trinitrophenol).
In the presence of sodium nitrite and hydrochloric acid, sulfanilc acid form a diazonium salt. This salt react with and is an indicator for thyrosine, histidine.
To obtain HNO2 from HNO3, you can reduce nitric acid (HNO3) using a reducing agent such as sulfamic acid or a metal like copper. The reduction reaction will convert the nitric acid to nitrous acid (HNO2). Make sure to carry out the reaction in a controlled environment with proper safety measures.
Acid + base conjugate base + conjugate acid
Acetamide is a weak base. It can undergo protonation to form the conjugate acid, acetic acid, in acidic solutions.
