Monosodium phosphate

Monosodium phosphate is like a special kind of salt. It's made of tiny little pieces called molecules that are really good at dissolving in water. And when you put it in water, it can make the water a little bit more acidic.

So, imagine you have a cup of lemonade that's too sweet. You could add a tiny bit of monosodium phosphate to make it a little more sour and less sweet.

But it's not just for lemonade! Scientists use monosodium phosphate to do lots of cool things, like make medicine or help plants grow better.

So basically, monosodium phosphate is like a special salt that's good at dissolving in water and can make things a little more acidic.
