Can NaOH be used in place of `NH_4OH` to precipitate the cations of group III in qualitative analysis?

Text Solution

AI Generated Solution

To determine whether sodium hydroxide (NaOH) can be used in place of ammonium hydroxide (NH4OH) to precipitate the cations of group III in qualitative analysis, we need to consider the properties of both bases and the requirements for the precipitation of these cations. ### Step-by-Step Solution: 1. **Identify Group III Cations**: - Group III cations in qualitative analysis typically include ferric ions (Fe³⁺), chromic ions (Cr³⁺), and aluminum ions (Al³⁺). 2. **Understand the Precipitation Process**: ...
