Determine the formulas of two salts that undergo hydrolysis Please select at least two options CaCl2 FeCl2 NH4Cl KCI NaCl

The salts that undergo hydrolysis are those that contain ions that can react with water to form weak acids or bases. Among the options provided, the salts that undergo hydrolysis are:<br /><br />1. $FeCl2$: Iron(II) chloride is a salt that undergoes hydrolysis in water. The hydrolysis reaction produces iron(II) hydroxide and hydrochloric acid.<br /><br />2. $NH4Cl$: Ammonium chloride is a salt that undergoes hydrolysis in water. The hydrolysis reaction produces ammonium hydroxide and hydrochloric acid.<br /><br />The other salts listed, such as $CaCl2$, KCl, and NaCl, do not undergo hydrolysis in water.
