Isoionic point
Okay kiddo, imagine you have a toy that can change color when it gets wet. Now, let's say the toy is made up of lots of tiny little pieces called "atoms". Some of these atoms have a positive charge and some of them have a negative charge, kind of like how magnets have a North and South pole.
Now, let's say you put the toy in a bowl of water. As the water touches the toy, the atoms start to interact with the molecules in the water. Some of the atoms on the toy will attract the positively charged molecules in the water, and some of them will attract the negatively charged molecules.
As more water touches the toy, the interactions between the atoms and the water start to balance out. This is because there are the same number of positively charged and negatively charged molecules in the water. When the number of positively charged and negatively charged molecules on the toy are also balanced, we call this the "isoionic point".
So, to put it simply, the isoionic point is the point at which the number of positive and negative charges on a toy or a substance are balanced out and neutralized. It's kind of like when you have an equal number of red and blue blocks and they cancel each other out to make a neutral, gray color.
