Problem 3.50

The compound \(\mathrm{XCl}_{4}\) contains 75.0 % CI by mass. What is the element X?

Text Transcription:

XCl4

Step-by-Step Solution:

Step 1 of 5) The compound XCl4 contains 75.0 % CI by mass. What is the element XStrong and Weak Acids and Bases Acids and bases that are strong electrolytes (completely ionized in solution) are strong acids and strong bases. Those that are weak electrolytes (partly ionized) are weak acids and weak bases. When reactivity depends only on H+1aq2 concentration, strong acids are more reactive than weak acids. The reactivity of an acid, however, can depend on the anion as well as on H+1aq2 concentration. For example, hydrofluoric acid (HF) is a weak acid (only partly ionized in aqueous solution), but it is very reactive and vigorously attacks many substances, including glass. This reactivity is due to the combined action of H+1aq2 and F-1aq2.Table 4.2 lists the strong acids and bases we are most likely to encounter. You need to commit this information to memory in order to correctly identify strong electrolytes and write net ionic equations. The brevity of this list tells us that most acids are weak. (For H2SO4, as we noted earlier, only the first proton completely ionizes.) The only common strong bases are the common soluble metal hydroxides. The most common weak base is NH3, which reacts with water to form OH- ions (Equation 4.10).
