That can’t be right; these two materials will react with each other
When these two substances are mixed, ammonia gas is released, and sodium chloride is formed in the solution. If there is enough sodium hydroxide, ammonium chloride cannot remain in the solution due to the reaction. The original poster had better find out in detail whether such an action is necessary.
It is to react out the ammonium chloride in the material
Now it is suspected that too little alkali was added, and the ammonium chloride in the material did not react. I’m not sure how many liters of base are needed to react out the ammonium chloride in the material; could you please calculate that for me? Thank you!

To ensure complete reaction of 75 KG of the material, 30% sodium hydroxide is required: 75/53 * 40/0.3 = 188 KG. I’m not sure if this is the result you need; it’s just a theoretical value, and there may be deviations in practice. If no other components in your material mixture can react with sodium hydroxide, then this figure can serve as a reference.
