'Conjugate' means ONE proton (H+) more (acid) or less (base) than the described acid or base respectively:So the conjugate acid of C6H5NH2 is C6H5NH3+ (phenylammonium cation), The conjugate base and conjugate acid for HS04 is: A solution has OH- = 1.3 x 10-2 M. Is this solution acidic, basic, or neutral? What is the conjugate base of #"phosphoric acid"#, #H_3PO_4#? Explain. Salt Compound Solution: The constituent ions that makes up an ionic (salt) compound may potentially have acidic/basic properties. The strongest acids ionize 100%. Other aniline dyes followed, such as fuchsin, safranin, and induline. It has one less H atom and one more charge. A solution of a weak acid reacts with a solution of a strong base to form the conjugate base of the weak acid and the conjugate acid of the strong base. Solved Write equations showing how each of the following By expressing your answer in a chemical formula you are defining the composition a class of (The value of Kb for . [29] The Bchamp reduction enabled the evolution of a massive dye industry in Germany. NaClO_4, How to classify solution either acidic, basic, or neutral? What are the conjugate acid and base of #NH_3#? Explain. In reactions where the acid is a hydrogen ion containing compound and the base is a hydroxide ion containing compound, water is also a product. Acid. The reaction of converting primary aromatic amine into diazonium salt is called diazotisation. to the empployees was very informative. Suppose a solution has (H3O+) = 1 x 10-2 M and (OH-) = 1 x 10-12 M. Is the solution acidic, basic, or neutral?
