#NH_4OH + HCl(aq) = NH_4Cl(aq) + H_2O(l)# no significant change can be noticed
How to make sure that a reaction is really taking place ?

Can you not use an indicator?

You titrate ammonia with hydrochloric acid......

#NH_3(aq) + HCl(aq) rarr NH_4Cl(aq) + H_2O#

At the stoichiometric endpoint, the pink dissipates to colourless. And there are other indicators to use if you don't like pink.

undefined You can use the following tests to make sure that a chemical reaction is occurring: 1. Look for any obvious changes, such as color changes, precipitate formation, gas evolution, or temperature changes; 2. Perform a chemical analysis both before and after the reaction to detect changes in chemical composition; 3. Monitor changes in acidity or basicity with indicators or pH meters; 4. Measure any changes in mass or volume of reactants and products; 5. Perform spectroscopic analysis to detect changes in molecular structure or bonding; 6. Conduct a conductivity test to detect the presence of ions; 7. For complex reactions, use methods like chromatography or spectroscopy.
