===end <nowiki>}</nowiki>-bracket issue ===

When input ends correctly with a <big>}</big>-bracket, like with <code><nowiki>A_{x}H_{1-x</nowiki>{{hl|1=<nowiki>}</nowiki>}}</code>, the final }-brackets are technically mixed up:

:<code><nowiki>{{</nowiki>chem2|A_{x}H_{1-x{{hl|1=<nowiki>}}}</nowiki>}}</code> → {{chem2|A_{x}H_{1-x}}} {{nay}}

The closing bracket {{code|1=<nowiki>{..}</nowiki>}} of input ''and'' end of temlate brackets {{code|1=<nowiki>}}</nowiki>}}.

*Solutions:

:::add empty pipe: <code><nowiki>{{chem2|..{..</nowiki>{{hl|1=<nowiki>}|}}</nowiki>}}</code> (empty parameter #2)

:::add parameters numbers 1 and 2 (empty): <code><nowiki>{{chem2|1=..{..</nowiki>{{hl|1=<nowiki>}|2=}}</nowiki>}}</code>

:::add a space: <code><nowiki>{{chem2|..{..</nowiki>{{hl|1=<nowiki>} }}</nowiki>}}</code>

:Result: <code><nowiki>{{</nowiki>chem2|A_{x}H_{1-x{{hl|1=<nowiki>} |}}</nowiki>}}</code> → {{chem2|A_{x}H_{1-x} |}} {{aye}}
