Override Biblatex style: missing pagination

Question

I would like to use the style=chem-angew but override that @article has no page prefix. I couldn't find any working solution yet (without doing manual changes on the bibliography or changing the style itself) and seek for help.

This is my working example:

\documentclass[12pt,a4paper]{article}                            
\usepackage[backend=biber,style=chem-angew]{biblatex}
\addbibresource{bib.bib}

\begin{document}
\cite{Eder.1983.types}
\cite{Fattahi.2005}

\printbibliography[heading=none]
\end{document}

bib.bib

@book{Eder.1983.types,
 author = {Eder, Franz Xaver},
 year = {1983},
 title = {Arbeitsmethoden der Thermodynamik: Band II Thermische und kalorische Stoffeigenschaften},
 address = {Berlin, Heidelberg},
 publisher = {{Springer Berlin Heidelberg}},
 pages = {125--261}
}

@article{Fattahi.2005,
 author = {Fattahi, Alireza and Kass, Steven R. and Liebman, Joel F. and Matos, M. Agostinha R. and Miranda, Margarida S. and Morais, Victor M. F.},
 year = {2005},
 title = {The enthalpies of formation of o-, m-, and p-benzoquinone: gas-phase ion energetics, combustion calorimetry, and quantum chemical computations combined},
 pages = {6116--6122},
}

Output:

The desired output has the prefix p.~/pp.~ for each item.

Answer 1

You can restore the original definition from biblatex.def, which prints the page prefix, as follows

\DeclareFieldFormat[article]{pages}{\mkpageprefix[bookpagination]{#1}}

Here the optional argument article applies this change only to @articles (since all other types have the prefix anyway). If you want to reset the format for all entry types, go with

\DeclareFieldFormat*{pages}{\mkpageprefix[bookpagination]{#1}}

In this case there is no difference between the two approaches (because @article was the only type with a definition different from the rest).

\documentclass[12pt,a4paper]{article}
\usepackage[backend=biber,style=chem-angew]{biblatex}

\DeclareFieldFormat[article]{pages}{\mkpageprefix[bookpagination]{#1}}

\begin{filecontents}{\jobname.bib}
