Title: net ionic equation for NaOH (aq)+ BaCl2(aq) reaction
Post by: wiscbrad on July 02, 2009, 10:25:42 PM
what is the net ionic equation for this reaction?
NaOH(aq)+BaCl2(aq)---->
i thought the products would be NaCl and Ba(OH)2 both of which are soluble but the reaction yields a white ppt after short time.

White precipitate comes from BaCO3.

As AWK wrote - NaOH is almost always contaminated with Na2CO3, as it absorbs CO2 from the atmosphere.
