0.05M ammonium acetate preparation
To prepare a 0.05m ammonium acetate solution, an appropriate amount of acetic acid and ammonium salt should be prepared. Take a clean container first to ensure that the solution is not contaminated.

Take a certain amount of acetic acid and pour it slowly into the container. The amount of acetic acid is accurately calculated according to the total volume and concentration of the solution prepared. Next, take an appropriate amount of ammonium salt and slowly add it to the container containing acetic acid. During this process, be careful to prevent the solution from splashing out.

Add it up and gently stir with a glass rod to promote the full reaction and dissolution of acetic acid and ammonium salt. When stirring, it can be seen that the particles in the solution interact and gradually become uniform.

Stir for a while until the solution is clear and transparent, with no solid residue, to obtain a 0.05m ammonium acetate solution. The resulting solution can be used for subsequent experiments or other purposes as needed. It needs to be properly stored to prevent its deterioration or volatilization to ensure the stability of its chemical properties.
