Example

Syntax

{{#ask:
 [[Has pKa value::+]]
 |?Has pKa value
 |format=plainlist
 |link=none
 |template=PKaValueTemplate
 |introtemplate=PKaValueTemplateHeader
 |outrotemplate=TableFooter
}}

Result

#	Chemical name	Chemical formula	pKa
1	Benzenesulfonic acid	C6H5SO3H	-2.5
2	Trichloroacetic acid	CCl3CO2H	0.77

  Note: The results show annotations for the "chemical formula" done via a template on a page and annotations for the "pKa value" done via a subobject embedded on the same page. While the "pKa value" is directly queried from the subobject on that page the "chemical formula" is queried via additional queries located in the query template ("PKaValueTemplate") from the same page on which the subobject holding the "pKa value" is embedded.

Templates used to create the example

• Template:PKaValueTemplate
• Template:PKaValueTemplateHeader
• Template:TableFooter
