Preparation of saturated lead acetate solution
To prepare a saturated lead acetate solution, prepare an appropriate amount of lead acetate first, and then take a clean container. Slowly inject an appropriate amount of water into the container, and the amount of water should be determined according to the amount of solution required.

Then, add lead acetate to the water gradually, and stir slowly with a glass rod to promote its dissolution. When adding lead acetate, it is best to add a small amount multiple times, and pay attention to observe its dissolution.

After adding lead acetate, stir for a while. If there are undissolved lead acetate particles in the solution, you can wait for a while, or heat it slightly to help dissolve, but the heating temperature should not be too high, so as not to affect the properties of the solution.

When the lead acetate is completely dissolved and there is no precipitation in the solution after standing, the solution is uniform and transparent, which is the saturated lead acetate solution. At this time, the solution can be moved to a suitable storage container and sealed to prevent it from changing its composition due to contact with air.
