To calculate Q_{sp} for PbCl_2, we use:

\[
Q_{sp} = [\text{Pb}^{2+}] \times [\text{Cl}^{-}]^2
\]

\end{document}

You need to use math mode:

Code: Select all

To calculate $Q_{sp}$ for $PbCl_2$

Or use the chemformula package:

Code: Select all

\documentclass{article}
\usepackage{chemformula}
\begin{document}
To calculate \ch{Q_{sp}} for \ch{PbCl2}, we use:
\[
\ch{Q_{sp}}	 = [\ch{Pb^{2+}}] \times [\ch{Cl-}]^2
\]
\end{document}
