What is the charge of HClO4?
The Cl atom would have three double bonds with three oxygen atoms and one single bond with OH, causing the formal charge of Cl to be 0 (7- (0+14/2)). All the oxygens will also have a formal charge of 0 because all of them will have two bonds, causing the overall HClO4 molecule to be neutral.
Is HClO the same as HOCl?
It is a weak acid, classified as an oxoacid, because it contains oxygen in its chemical formula. In respect to this, is HOCl and HClO the same? HOCl and HClO are exactly same. This is molecular formula of hypochlorus acid. It is also known as Hydrogen hypochlorite or Chlorine hydroxide as per given molecular formula.
What is the formal charge on Cl in HClO4?
There are 4 O atoms so the total negative charge is -8. There is 1 H atom with +1 charge, so the remaining Cl atom must be +7 to charge balance the -8 negative charge. I would like to stress again that if you want to have the real charges of the atoms in a chemical compound you have to carry out quantum chemical calculations.
Does HNO3 have a charge?
You will have neutral molecule of HNO3. Well the formal charge on the N is +1 because the HNO3 has 3 things bonding to the N and all of them are single bonds meaning that only one bond is made with all of the atoms.

How are hypochlorites produced?
Solutions of hypochlorites can be produced by electrolysis of an aqueous sodium chloride solution. The composition of the resulting solution depends on the pH at the anode. In acid conditions the solution produced will have a high hypochlorous acid concentration, but will also contain dissolved gaseous chlorine, which can be corrosive, at a neutral pH the solution will be around 75% hypochlorous acid and 25% hypochlorite. Some of the chlorine gas produced will dissolve forming hypochlorite ions. Hypochlorites are also produced by the disproportionation of chlorine gas in alkaline solutions.

Is hypochlorous acid a compound?
Hypochlorous acid is a compound that is unstable in its pure form, so it always has to exist in solution. This means it has to exist in a solution with water as a solvent. Hypochlorous acid is a weak acid and an oxoacid because it is an acid that contains oxygen. It is formed when chlorine Cl 2 is dissolved in water H2O.
Is HClO a weak acid?
Hypochlorous acid is unstable in its pure form, so it exists in a solution with water. It is a weak acid, classified as an oxoacid, because it contains oxygen in its chemical formula.
Is hypochlorous acid a neutral molecule?
We know that hypochlorous acid is a neutral molecule, so its total charge is zero. Because the formal charge we calculated is also zero, our Lewis structure for hypochlorous acid is correct. Hypochlorous acid has a chemical formula of HClO. It has one hydrogen (H) atom, one chlorine (Cl) atom and one oxygen (O) atom.
Characteristics of HClO
The hypochlorous acid is classified as a weak acid; its pKa value is relatively high (pKa = 7.53). The pKa value is the negative log base ten of the acid dissociation constant. Therefore, the higher than pKa value, the lower the acid's dissociation, the weaker the acid.
Uses of HClO
The uses of hypochlorous acid are not limited to disinfecting surfaces and killing germs; this oxoacid is used in various other applications. Hypochlorous acid is an ingredient in various consumer items, including deodorants.
Production of HClO
Hypochlorous acid is formed when chlorine {eq}Cl_2 {/eq} partially dissociates in water {eq}H_2O {/eq} to form hypochlorite ion {eq}ClO^- {/eq}. This eventually gets protonated into HClO when oxygen forms a bond with hydrogen from the water molecules. The equation that depicts the formation of hypochlorous acid is shown as:
Which structure has zero formal charges?
The right-hand structure wins; it has zero formal charges, while the left has ± 1. The following point is now longer needed. For structures that cannot avoid formal charges it is more stable to have formal negative charges on electronegative atoms and formal positive ones on electropositive atoms.
Is O H C L a minima?
Any other structure, for example linear or bent O H C l, are no minima on the potential energy surface. They might exist as excited or transition states, but they are incredibly short lived. One only has to care about these species when dealing with complex gas phase reactions. (There is now way they could be stable in solution.)
Overview
Mode of disinfectant action
E. coli exposed to hypochlorous acid lose viability in less than 0.1 seconds due to inactivation of many vital systems. Hypochlorous acid has a reported LD50 of 0.0104–0.156 ppm and 2.6 ppm caused 100% growth inhibition in 5 minutes. However, the concentration required for bactericidal activity is also highly dependent on bacterial concentration.
In 1948, Knox et al. proposed the idea that inhibition of glucose oxidation is a major factor in the …

In a clinical test, hypochlorous acid water was tested for eye irritation, skin irritation, and toxicity. The test concluded that it was non-toxic and nonirritating to the eye and skin.
In a recent study, a saline hygiene solution preserved with pure hypochlorous acid was shown t…
Commercialisation
For disinfection, despite being discovered a long time ago, the stability of hypochlorous acid water is difficult to maintain. In solution, the active compounds quickly deteriorate back into salt water, losing its disinfecting capability, which makes it difficult to transport for wide use. Despite its stronger disinfecting capabilities, it is less commonly used as a disinfectant compared to bleach and alcohol due to cost.
