# What are the coefficients for the equation Al_2(SO_4)_3 (aq) + KOH(aq) -> Al(OH)_3(s) + K_2SO_4(aq)?

$A {l}_{2} {\left(S {O}_{4}\right)}_{3} \left(a q\right) + 6 K O H \left(a q\right) \rightarrow 2 A l {\left(O H\right)}_{3} \left(s\right) \downarrow + 3 {K}_{2} S {O}_{4} \left(a q\right)$
Is this equation balanced? How do you know? All I have done here is practise $\text{stoichiometry}$, and ensured $\text{garbage out"="garbage in}$.
