PbNO32 Na2CrO4 NaNO3 PbCrO4 Instructions and examples below may help to solve this problem You can always ask for help in the forum. When u say Pb II it means its valency is 2 And CrO4 also has a valency of -2 So both satisfy their valency needs and form a covalent bond. Therefore when the soluble salts lead II nitrate and potassium chromate are mixed insoluble lead II chromate forms and precipitates out K sp 28 x 10 -13.
It is an ionic compound composed of the lead IV cation Pb4 and the chromate anion CrO42-Pb4 2CrO42- — PbCrO42. Molecular weight of Pb ClO42 or grams This compound is also known as Lead II Perchlorate. It has a vivid yellow color and is insoluble in all solvents.
ZnCrO4 PbNO32 ZnNO32 PbCrO4. Compound Summary Lead chromate oxide Pb2 CrO4O. The SI base unit for amount of substance is the mole.
This activity was created by a Quia Web subscriber. As both have a valency of 2 they get cancelled -. Two polymorphs of lead chromate are known orthorhombic and the more stable monoclinic form.
Equation PbNO32Na2CrO4NaNO3PbCrO42 is an impossible reaction Please correct your reaction or click on one of the suggestions below. Learn more about Quia. Pickerington High School Central.
Pb is 4 NO3 is -1 and there are 4 NO3 so it is -4 K2 is 2 2 1 2 and CrO4 is -2.
