Chemistry - Chemical elements or compounds with yellowish white color

Solution 1:

1. Aluminium(III) chloride - often described as white but samples is sometimes contaminated with iron(III) chloride giving it a light yellow color
2. Antimony(V) oxide - pale yellow solid
3. Bismuth(III) oxide - light yellow solid
4. Rhodium(III) oxide - lemon yellow
5. Cerium(IV) oxide - pale yellow-white compound
6. Dysprosium(III) nitrate - white to pale yellow
7. Holmium(III) oxide- Color depends on lighting condition. In daylight, it is tannish light yellow; Under trichromatic light, it is fiery orange red (Thanks @EdV)
8. Samarium(III) oxide - light yellow
9. Silver(I) iodide - samples can have a range of color(white to pale yellow to yellow) due to impurity and photosensitization
10. Selenium(IV) chloride - white to faint yellow volatile solid
11. Gold(III) chloride - pale yellow to yellow
12. Potassium Telluride - pale yellow
13. Thallium(III) bromide - pale yellow
14. Some vanadate salts are light yellow

Bromium nitrate is pale yellow but not confirmed. Silver(I) bromide and lead(II) bromide are light yellow and white cream colored respectively.

Solution 2:

Calcium hypochlorite is an example of such a yellowish white compound.

Another example would be Silver Bromide
