What is the formula for the compound formed by lead ions and chromate ions?
Lead ions = Pb2+Chromate ions = CrO4-2Compound they form is Lead(II) chromate = PbCrO4
Why is lead chromate not soluble in water?
Lead chromate has a low solubility in water due to the strong electrostatic forces between the lead and chromate ions, which hold the compound together in a solid form. These forces prevent the ions from separating and dissolving in water, resulting in poor solubility.
Will NaCrO4 dissolve in water?
Na2CrO4 will dissolve in water as will all sodium compounds.
How chromate ions are converted into dichromate ions?
In an acidic solution chromate ions are converted into dichromate ions.
When potassium chromate dissolves in water what ions are produced?
When potassium chromate dissolves in water, it produces potassium ions (K⁺) and chromate ions (CrO₄²⁻).
What is the formula for the compound formed by lead(ii) ions and chromate ions?
Lead ions = Pb2+Chromate ions = CrO4-2Compound they form is Lead(II) chromate = PbCrO4
Is lead chromate soluble?
Lead chromate is sparingly soluble in water; it is slightly soluble in acids and more soluble in alkalis. However, lead chromate is considered highly toxic and should be handled with care due to its potential environmental and health risks.
What is produced when ammonium and chromate ions form?
When ammonium and chromate ions form a reaction, ammonium chromate is produced. Ammonium chromate is a yellow-orange solid compound that is typically used in analytical chemistry and as a chemical reagent.
Is cromate soluble?
Chromate salts are typically soluble in water, except for certain heavy metal chromates like lead chromate and silver chromate, which are insoluble.
Is lead chromate soluble in oils?
It is not soluble in oils.
Why silver nitrate reacts with chloride ions before chromate ions in Mohr's method?
In Mohr's method, silver nitrate reacts with chloride ions before chromate ions due to the differing solubilities of their respective silver salts. Silver chloride (AgCl) is highly insoluble in water, leading to its immediate precipitation upon contact with chloride ions. In contrast, silver chromate (Ag2CrO4) is less soluble, meaning that the reaction with chromate ions occurs only after all available chloride ions have been precipitated as AgCl. This selective reaction allows for accurate titration and detection of chloride ions.
Is ammonium chromate soluble?
Yes, ammonium chromate is soluble in water, with a solubility of 60 g/L at room temperature.
