Explain. Is an aqueous solution with OH- = 9.42 x 10-8 M acidic, basic, or neutral? Salts that form from a strong acid and a weak base are acid salts, like ammonium chloride (NH4Cl). I think the 'strong base if weak conjugate acid' argument only really works if the conjugate acid is less acidic than water. View all equations with C6H5NH2 as reactant, View all equation with C6H5NH3Cl as product. Wiki User. Explain. Explain. Direct link to Florence Tsang's post See the chloride ion as t, Posted 6 years ago.

Aniline hydrochloride, C6H5NH3Cl, is a salt that, after it dissociates in water, has a component that acts as a weak acid (Ka = 2.4 105 ). On the basis of ph we will classify all the options. The list of strong acids is provided below. NH3 + HCl -----> NH4+ + Cl-Instead of ammonia, a nitrogen-base can be an amine such as methylamine, CH3NH2. C6H5NH3+, conjugate base is a weak base, therefore it is potentially acidic NO2-, conjugate acid is a weak acid, therefore the salt is also potentially basic However, since the Ka > Kb, the solution must be acidic So it has both nature acidic on basic in its constituent, it will act as a neutral soul. 2, will dissolve in 500 mL of water. The kind of salt formed depends on the acid and base that combined to yield the salt.. We have to know that the pH of a salt solution depends on the acid and base that reacts to form the salt..

Since Kb for NH3 is greater than the Ka for HCN,( or Kb CN- is greater than Ka NH4+), this salt should have a pH >7 (alkaline). To tell if KCl forms an acidic, basic (alkaline), or neutral solution we can use these three simple rules along with the neutralization reaction that formed KCl. The overall salt does not donate protons, the CH3NH3+ ion does (to form H3O+) when the salt is dissociated in water. Determine whether a 0.0100 M {eq}C_6H_5NH_3Cl Chapter 16, Exercises #105. Explain. What are the chemical and physical characteristic of HCl (hydrogen chloride)? Explain. i. Is an aqueous solution with OH- = 3.47 x 10-6 M acidic, basic, or neutral? About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features Press Copyright Contact us Creators . Identify whether a solution of each of the following is either acidic, basic or neutral. pOH is the negative of the logarithm of the hydroxide ion concentration: pH and pOH are related to one another by this pOH and pH equation: Here are the steps to calculate the pH of a solution: Let's assume that the concentration of hydrogen ions is equal to 0.0001 mol/L. Is an aqueous solution with H+ = 6.65 x 10-3 M acidic, basic, or neutral? (a) Identify the species that acts as the weak acid in this concentration of our acetate anion, here, so we're gonna write: 0.25 molar, for the initial concentration of the acetate anion. So if we lose a certain Explain. Calculate [H^+] for each of the following solutions and indicate whether the solution is acidic, basic, or neutral. a. Let's do another one. The equivalence point [Hint: at this point, the weak acid and Because the nitrogen atom consists of one lone pair which can be used to So, we could find the pOH from here. So over here, we put 0.050 - X. hydrochloride with a concentration of 0.150 M, what is the pH of So a zero concentration Is an aqueous solution with pOH = 7.98 acidic, basic, or neutral? NaClO_4, How to classify solution either acidic, basic, or neutral? c6h5nh3cl acid or base. Explain. So we just need to solve for Kb. Is a solution of the salt KNO3 acidic, basic, or neutral?
