Rubber gloves and other chemical resistant protective clothing are necessary when handling concentrated ammonium hydroxide.
<h3 /><h3>Why it is necessary to handle concentrated solution of ammonium hydroxide with care ?</h3>
- Ammonia is an irritant and corrosive to the skin, eyes, respiratory tract and mucous membranes.
- May cause severe chemical burns to the eyes, lungs and skin.
- Skin and respiratory related diseases could be aggravated by exposure.
The extent of injury produced by exposure to ammonia depends on the duration of the exposure, the concentration of the liquid or vapor and the depth of inhalation.
Hence, Rubber gloves and other chemical resistant protective clothing are necessary when handling concentrated ammonium hydroxide.

Answer:
a compound can experience a chemical change if foreign body are in troduced
It is a decomposition reaction
KCl is neutral because KOH is a strong base and HCl is a strong acid
To determine if the salt is neutral, acidic or basic, determine how the salt was made, or from which acid and base it was derived. Once we have determined how the salt was made, determine if the acid and base are both strong, weak or one of each. If both are strong (e.g. NaOH + HCl), then the salt (NaCl) is NEUTRAL. If the base is strong and the acid is weak (KOH + HCN), then the salt (KCN) is BASIC. IF the base is weak and the acid is strong (NH3 + HCl), then the salt (NH4Cl) is ACIDIC. If both the base and the acid are weak (NH3 + CH3COOH), then then salt (CH3COONH4) will have a pH determined by which is stronger (the acid or the base) and this will depend on the Ka of the weak acid compared to the Kb of the weak base.
KCl is neutral because KOH is a strong base and HCl is a strong acid NaCN is generally basic because NaOH is a strong base and HCN is a very week acid. NH4NO3 is usually acid because HNO3 is a strong acid and NH4OH is a week base
CH3COONH4 is exactly neutral because both NH4OH ad CH3COOH are respectively week base and week acid. Moreover, the Ka of acetic acid is exactly equal to the Kb of NH4OH
