Which type of metal compounds are nomenclate according to stock notation nomenclature method ?
Stock notation is used for naming compounds of metals that have more than one possible oxidation state. For example, FeCl2 is named iron(II) chloride, and FeCl3 is named iron(III) chloride.
Molecular formula of sodium chromate (VI) is
The molecular formula of sodium chromate (VI) is $Na_2CrO_4$. Sodium chromate is an inorganic compound with the formula $Na_2CrO_4$. It is a yellow crystalline solid that is often used in industrial applications.
What is the name of $ K_2Cr_2O_7 $ according to stock notation nomenclature method ?
The name of $K_2Cr_2O_7$ according to the stock notation nomenclature method is Potassium dichromate (VI). The (VI) indicates the oxidation state of chromium, which is +6 in this compound.
What is the name of $ TiO_2$ , according to stock notation nomenclature method ?
The name of $TiO_2$ according to the stock notation nomenclature method is Titanium (IV) oxide. The (IV) indicates the oxidation state of titanium, which is +4 in this compound.
Which of the following is the true for $ Fe_3O_4 $ ?
In $ Fe_3O_4 $, iron exhibits two different oxidation states: +2 and +3. There are two Fe atoms with +3 oxidation state and one Fe atom with +2 oxidation state. This is why the ratio of atoms with oxidation states +2 and +3 in $ Fe_3O_4 $ is 1:2.
Which of the following is the wrong for $ Fe_3O_4 $ ?
The correct proportion of FeO and $ Fe_2O_3 $ in $ Fe_3O_4 $ is 1:1, not 1:2. Hence, the statement that the proportion of FeO and $ Fe_2O_3 $ is 1:2 is incorrect.
The no. of peroxy ring in $ CrO_5$ is
Which of the following compound possesses peroxide $ (O_^{2–} or [–O–O–]^{2–}) $ in?
Barium peroxide (BaO2) contains the peroxide ion (O2^2-). The structure of BaO2 consists of Ba^2+ cations and O2^2- anions. This can be remembered by noting that BaO2 is commonly used as a source of peroxide in inorganic chemistry.
Which of the following compound possesses peroxide $ (O_2 ^ {1–}) $ ion ?
Barium peroxide (BaO2) contains the peroxide ion (O2^2-), not superoxide (O2^-). The confusion may arise because O2^- (superoxide) and O2^2- (peroxide) are closely related, but BaO2 specifically has the peroxide ion (O2^2-).
What is the oxidation No. of Cr in $ CrO_5, K_2Cr_2O_7, K_2CrO_4 $ or in chromium pentoxide , potassium dichromate, potassium chromate respectively
The oxidation number of chromium in CrO5, K2Cr2O7, and K2CrO4 are +6, +6, and +6, respectively. This can be determined by using the rules for oxidation states and the known structures of these compounds. For example, in K2Cr2O7 (potassium dichromate), chromium is in the +6 oxidation state due to the balancing of charges with oxygen and potassium.
