Web(Ksp values more than 10-20) so they can be precipitated by relatively high amounts of sulfide ion; this can be achieved by adding a basic solution of H2S. Group IV (Mg2+, Ca2+, Sr2+, Ba2+) cations, as well as all of the above groups, produce insoluble carbonates so they can be precipitated by the addition of carbonate once the ions of the WebFabric for.dyeing must be uniformly neutral; a pH no higher than 7 should be recorded when samples have been thoroughly extracted in boiling distilled water. Alkalinity can be corrected by careftıll addition of dilute acetic acid, but an excess should be avoided since carboxyl ions can catalyse the hydrolysis of many rective dyes in solution.
