20 gru 2023 · Chromate is the salt of chromic acids that contains chromate anion. It is a chromium oxo anion & a divalent inorganic anion generated by removing two protons from chromic acid. Its chemical formula is CrO42-. It is one of the numerous polyatomic ions which are used to create insoluble salts.
For each of the following questions, determine whether the compound is ionic or covalent and write the appropriate formula for it. The following are a good mix of naming and formula writing problems to help you get some practice.
Chromate is the oxoanion which results from the removal of protons from chromic acid. It is also called chromium oxoanion or divalent inorganic anions. The most commonly used chromate salts are sodium and potassium salts. Table of Contents. Chromate Structure; Physical Properties of Chromate; Chemical Properties of Chromate; Uses of Chromate
In this lab we will gain experience in predicting charges and naming monatomic cations and anions. We will be introduced to polyatomic ions and predict the ratios in which they form ionic bonds. A monatomic ion is an ion consisting of one atom that either gained or lost electrons.
