# How do you write an equation for the process "Sodium thiosulfate dissolves in water"?

Dec 8, 2016

$N {a}_{2} {S}_{2} {O}_{3} \left(s\right) r i g h t \le f t h a r p \infty n s 2 N {a}^{+} \left(a q\right) + {S}_{2} {O}_{3}^{2 -} \left(a q\right)$

#### Explanation:

$\left(a q\right)$ stands for the aquated sodium ion, or the aquated thiosulfate ion; the ion surrounded by several water molecules. This is understood to be in solution.
