Text Formatting ⇒ space before :

[nicr]

Hello every body,

When I write
HF:HNO$_3$:H$_2$O
15:1:2,5
I get
HF :HNO3 :H20
15 :1 :2,5
The problem is the space before :. Please, would someone know why I get a space before each : that I wrote?

[Johannes_B]

Where is the minimal working example?

Thank you Johannes_B,
I found that I have

Code: Select all

\usepackage{caption}
\DeclareCaptionLabelSeparator{colonfr}{~: }

This should be the reason.
Thank you again

You might want to check out package chemformula which makes typing chemical formulas much easier.

Code: Select all

\documentclass{article}
\usepackage[french]{babel}
\usepackage{chemformula}
\begin{document}
\ch{HF} and \ch{HNO3} and \ch{H2O}

HF:HNO$_3$:H$_2$O

{\sffamily \ch{HF} and \ch{HNO3} and \ch{H2O}

\NoAutoSpacing
HF:HNO$_3$:H$_2$O}
\end{document}

When I write
HF:HNO$_3$:H$_2$O
15:1:2,5
I get
HF :HNO3 :H20
15 :1 :2,5

Let me guess: you're using babel with French?

Code: Select all

\documentclass{article}
\usepackage[french]{babel}
\usepackage[T1]{fontenc}
\begin{document}
HF:HNO$_3$:H$_2$O
15:1:2,5
\end{document}

The solution: use proper markup and mathmode:

Code: Select all

\documentclass{article}
\usepackage[french]{babel}
\usepackage[T1]{fontenc}
\usepackage{chemformula}
\begin{document}
$\ch{HF}:\ch{HNO3}:\ch{H2O}$
$15:1:2{,}5$
\end{document}
