Zinc sulfide (ZnS), copper chloride-doped - …

The oral absorption of the slightly soluble zinc oxide has been shown to be 60% of that of the soluble zinc compounds. This corresponds to approximately 12-18%. No oral absorption information is available for the remaining slightly soluble and insoluble zinc compounds (i.e., ZnO, Zn(OH) 2, Zn 3 (PO 4) 2, ZnCO 3, Zn, ZnS). However, considering ...

Zinc sulfide (ZnS), copper chloride-doped - …

Therefore, the PNECs as derived for the soluble zinc compounds (zinc ion related) are also relevant for the insoluble ZnS, because they are expressed as “zinc ion”, not as the test compound. It is emphasised that the aquatic toxicity test results obtained on soluble zinc compounds are not relevant for ZnS.

2019-6-21 · 3. A solute is said to be insoluble if its solubility is less than 0.1 g/100 g of water (0.1 g/100 mL water at 25°C) A solute is said to be slightly soluble, or sparingly soluble, if its solubility is between 0.1 g/100 g of water and 1.0 g/100 g (between 0.1 g/100 mL water and 1.0 g/100 mL at 25°C)

Solubility Rules - Chemistry LibreTexts

Hydroxide salts of Group II elements (Ca, Sr, and Ba) are slightly soluble. Hydroxide salts of transition metals and Al 3 + are insoluble. Thus, Fe(OH) 3, Al(OH) 3, Co(OH) 2 are not soluble. Most sulfides of transition metals are highly insoluble, including CdS, FeS, ZnS, and Ag 2 S. Arsenic, antimony, bismuth, and lead sulfides are also insoluble.
