What is the name for mno4?

A permanganate is the general name for a chemicalcompound containing the manganate(VII) ion, (MnO 4. ). Because manganese is in the +7 oxidation state,the permanganate(VII) ion is a strong oxidizing agent. The ion hastetrahedral geometry.

Why is potassium chromate used as an indicator?

It is also used as an indicator in precipitationtitrations with silver nitrate and sodium chloride (they can beused as standard as well as titrant for each other) aspotassium chromate turns red in the presence of excess ofsilver ions.

Is NaOH a strong base?

Sodium hydroxide (NaOH) is strong base because it fully dissociates in water to produce hydroxide ions. While ammonia (NH3) is weak base because it accepts protons from water to produce fewer hydroxide ions in solution. While weak bases produce fewer hydroxide ions, making the solution less basic.

What is the charge of chromium?

Chromium exhibits a wide range of oxidationstates, but chromium being ionized into a cation with apositive 3 charge serves as chromium’s most stableionic state.

Is o2 a polyatomic ion?

Polyatomic Ions. A polyatomic ion is anion composed of more than one atom. The ammonium ionconsists of one nitrogen atom and four hydrogen atoms. Thehydroxide ion (OH) is an oxygen atom (red)bonded to a hydrogen atom.

Is h2cr2o7 a strong acid?

The term chromic acid is usually used for a mixture made by adding concentrated sulfuric acid to a dichromate, which may contain a variety of compounds, including solid chromium trioxide. Chromic acid features chromium in an oxidation state of +6 (or VI). It is a strong and corrosive oxidising agent.

What is chromate used for?

It is primarily used as a corrosion inhibitor,primer, decorative finish, or to retain electrical conductivity.The process is named after the chromate found in chromicacid, also known as hexavalent chromium, the chemical most widelyused in the immersion bath process whereby the coating isapplied.

Is h2cro4 a strong acid?
