1. The beakers below contain an aqueous solution of three different acids, HX, HY, and HZ, respectively, and represent the solutions at equilibrium. The initial concentrations of all three solutions were the same. Assume the volume of each solution is the same. HX = 00 HY = OO HZ = 00 H,O' = H,o°= H,o'= %3D %3D %D Do

Which is a base?   Question 16 options:   KCl   NaCl   HCl   NaOH

In 1903, Arrhenius theorized that a compound could be predicted to behave as an acid or a base by inspecting its chemical formula. For each of the following sentences, select the word that completes the statement correctly about Arrhenius' theory. If you need to review this concept, select here. 1. Arrhenius defined bases as ionic hydroxide compounds that dissociate into individual cations and negative hydroxide ions in solution. 2. The formula of an Arrhenius base begins 3. Arrhenius defined 4. The formula of an Arrhenius acid begins with a hydrogen ion. ◆ as compounds that ionize into positive hydrogen ions and anions in solution. with a hydrogen ion or if it is an organic acid, ends with a -COOH.
