Q:According to the Lewis theory, which one of the following species would be expected to react as a, A:According to Lewis theory, Acid is species which accepts electrons and Base is species which, Q:Calculate the percent ionization of propionic acid 1C2H5COOH2 in solutions of each of the following, A:The percent ionization of propionic acid is to be calculated, Q:Which of the following is a Lewis acid? water, A:According to Arrhenius , an acid is defined as any species that gives H+ ions in water . For this reason it cannot be handled in glass test tubes or apparatus during laboratory work. Q:Determine whether solutions of the following salts are acidic, basic, or neutral at 25oC: (a), A:Given : Because this reaction produces OH-, the resulting solution will be basic and cause a pH>7. When it comes to identifying a basic salt, there are several key characteristics that you can look for. ), A:Solution - View this solution and millions of others when you join today! To do this test, you will need: - LiOH Video Explanation Was this answer helpful? Salt. [H3O+] = 8.87109M Assume, A:Strongest base: CH3NH2Middle base: NaCN, Weakest base: NaCl, Q:Chlorobenzene, C6H5Cl, is a key intermediate in the manufacture of dyes and pesticides. NH4I This means the Kb will be very small. Salts are composed of related numbers of cations (positively charged ions) and anions (negative ions) so that the product is electrically neutral (without a net charge). answered 04/08/21, Ph.D. University Professor with 10+ years Tutoring Experience. Where does this (supposedly) Gibson quote come from? Salts, when placed in water, will often react with the water to produce H3O+ or OH-.
