Determine the formulas of two salts that do not undergo hydrolysis Please select at least two options NH4NO3 FeCl3 CsCI CaCl2 NaF

The salts that do not undergo hydrolysis are those whose ions do not react with water. Among the options provided, the salts that do not undergo hydrolysis are:<br /><br />1. $NH4NO3$ (Ammonium nitrate): The ammonium ion ($NH4^+$) and the nitrate ion ($NO3^-$) do not undergo hydrolysis in water.<br /><br />2. $CaCl2$ (Calcium chloride): The calcium ion ($Ca^{2+}$) and the chloride ion ($Cl^-$) do not undergo hydrolysis in water.<br /><br />Therefore, the correct options are $NH4NO3$ and $CaCl2$.
