Mar 1, 2017 · After doing the Lewis structure of Bromate Ion and in order to find the molecular geometry using VESPR method, we have: central atom: Br. Electrons of the central atom: 7. Electrons that contribute the 3 Oxygens : 3. Electrons that contribute the central atom for the π bonds: -2. Charge of ion (negative) : 1. Total electrons : 9

Aug 18, 2019 · Permanganate ion reacts with bromide ion in basic medium to give manganese dioxide and bromate ion. Write the balanced ionic equation for the reaction. Please balance the equation using the oxidation number method. The skeletal ionic equation is: $$\ce{MnO4-(aq) + Br-(aq) -> MnO2(s) + BrO3-(aq)}$$

Feb 11, 2019 · Bretherick’s Handbook of Reactive Chemical Hazards lists bromine trioxide $\ce{BrO3}$ structure as the one composed of cationic and anionic parts [1, p. 116]:

According to this article, the city of Los Angeles (in the USA) is facing a problem where bromate, a suspected carcinogen, has been forming in their open water supplies. They believe that the formation of bromate has to do with exposure to sunlight, and are now distributing millions of "shade balls" into water supplies in order to block the ...

Aug 23, 2019 · From a theoretical viewpoint we would expect the Br to be sp3 hybridized, because in the HBr molecule the Br atom has 4 pairs of electrons around it (the 3 lone pairs plus the bonding pair), and symmetry (plus the repulsion of electrons for each other) tells us to expect that 4 pairs of electrons arrange themselves in a tetrahedron, and as you know we explain a …

Aug 18, 2018 · Oxidation is the loss of electrons or an increase in oxidation number by a molecule, atom, or ion. Reduction is the gain of electrons or a decrease in oxidation number by a molecule, atom, or ion. To calculate the oxidation number of $\ce{Br}$ in $\ce{KBrO3}$:

Dec 20, 2015 · Now I know this is just a question about the common ion effect. I know how to do the question if silver ions are already present in the solution then silver acetate is added. Also given the concentration of acetate ions, I can easily calculate the pH. The real problem with this question is that you are dissolving 2 salts which are both in ...

Sep 4, 2016 · So, what causes it much higher stability? Maybe it is their ion size. The benzenediazonium cation and fluoroborate anion are of same size resulting their stability[citation needed?]. Or maybe it is due to the resonance of benzenediazonium cation. But when you apply heat to the salt, it is bound to decompose, maybe because of two reasons.

Feb 8, 2017 · My thinking is based on the fact that oxygen is always 2, therefore iodine has 3*2-1=5. Two double bonds and one single bond with oxygen are present in iodate ion. Iodine has oxidation number 7 in periodate ion as 4*2-1=7. Where is my error? EDIT:

I suppose that you know how to find the atomic electron configuration for Br which is $\mathrm{1s^22s^22p^63s^23p^64s^23d^{10}4p^5}$. Now for ions, it is really simple. All you have to do is look at if the ion is a cation or an anion. If it is an anion then add the same amount of electrons as the number of the charge.
