# Question #3fc1b

Ammonium nitrate, $N {H}_{4} N {O}_{3}$, is highly soluble in water. Even at ${0}^{\circ} \text{C}$, you can dissolve more than 100 g of ammonium nitrate in 100 g of water.
In this solubility diagram, ammonium nitrate is represented by a $\textcolor{p u r p \le}{\text{purple line}}$. As you can see, its solubility increases significantly with an increase in temperature.
At ${30}^{\circ} \text{C}$, you can dissolve close to 250 g of ammonium nitrate in 100 g of water. At ${70}^{\circ} \text{C}$, you can dissolve close to 470 g per 100 g of water.
