What is NaIO4?
What is NaIO4?
Sodium periodate (NaIO4) breaks apart 1,2-diols (“vicinal” diols) to form aldehydes and ketones. In this respect it’s the same as periodic acid (HIO4) and lead tetra-acetate [Pb(OAc)4]. Notice what’s happening to NaIO4 here – it’s becoming reduced from iodine(VII) to iodine(V).
What is periodate oxidation?
Periodate oxidation is a classic reaction in carbohydrate chemistry used to split bonds between vicinal carbons bearing unsubstituted hydroxyl or amino groups (17). Extensive periodate oxidation also splits the non-sulfated GlcA residue within the pentasaccharide of the antithrombin binding domain (ATbd) (Fig.
What is Lemieux reagent?
The conversion of an olefin into two individual aldehydes by means of an oxidative cleavage of a carbon‐carbon double bond with osmium tetraoxide‐sodium periodate is known as the Lemieux–Johnson oxidative cleavage and the combination of osmium tetraoxide and sodium periodate is referred to as Lemieux–Johnson reagent.
What is the formula for potassium periodate?
KIO4
What is the formula for potassium?
As they are ionically bonded together, potassium has an oxidation number of +1 and iodide is -1. Since there is a tendency to gain or lose electrons to achieve a stable state we get the formula KI….Potassium Iodide Chemical Formula.

Is silver acetate a precipitate?
Solubility of Silver Acetate. Description: Mixing silver nitrate and sodium acetate solutions of appropriate concentrations does not yield a precipitate. When a concentrated solution of either silver ion or acetate ion is added to the mixture, a precipitate forms.
Does acetic acid dissolve silver?
Ordinary silver dissolves with difficulty in a 1:1 mixture of 5% acetic acid and 3% hydrogen peroxide. However, “anodizing” the silver in a salt water bath corrodes the surface, allowing it to dissolve in the aqueous solution.
Is silver chloride soluble or insoluble?

Why is KMnO4 oxidizing agent?
For the standardization of KMnO4 solutions, reduction by oxalic is often used. 8. Because it contains Manganese in its highest oxidation state of +7. This compound is a strong oxidizing agent because elements become more electronegative as the oxidation states of their atoms increase.
Can you buy potassium permanganate at Walmart?
Pro Potassium Permanganate KMnO4 (6 – 2 lb bottles) – Walmart.com – Walmart.com.
What happens when you mix hydrogen peroxide and potassium permanganate?
When you add the potassium permanganate, it reacts with the hydrogen peroxide to produce oxygen in small “pockets”. These pockets of oxygen increase the intensity of the reaction and you get the cannon fire noise as the pockets of oxygen hit the flame.
