Ammonium Hydroxide
There are many chemicals available on the market today that are suitable for use as neutralization chemicals. The most commonly used chemicals are discussed in an article available here: Neutralization Chemicals.
Ammonium Hydroxide NH4OH
Ammonium Hydroxide (NH4OH): One of the more commonly produced chemicals in the United States, ammonium hydroxide is a poor choice for a neutralizing chemical. It is relatively expensive, hard to handle, can evolve noxious and corrosive gasses and is a relatively weak base. Nonetheless, we still receive inquiries, from time-to-time about using NH4OH for the neutralization of acids. Although we can and will use NH4OH as a neutralizing chemical, we generally recommend against its use. The storage tank and the treatment tank must be well ventilated and leaks can pose many hazards.
Ammonium hydroxide is not normally a good choice for a neutralization agent for acids, due to cost and safety reasons.
