The acids of chlorine having oxygen are the oxy acids , they are four ,HClO hypochlorous acid, HClO2 chlorous acid, HClO3 chloric acid and HClO4 perchloric acid, in these acids the oxidation no of oxygen are +1 ,+3 ,+5 and +7 respectively, the hypochlorous acid only exists in water. with the rise of no of oxygen atoms the acidic strength of oxy acids increases so perchloric acid is the strongest acid among these.
+5. In oxyacids, oxygen has an oxidation state of -2 and hydrogen an oxidation state of +1. Therefore, the single chlorine atom must have an oxidation state of +5 for the total oxidation states to add to zero.+5. In oxyacids, oxygen has an oxidation state of -2 and hydrogen an oxidation state of +1
Oxyacids consist of nonmetal elements combined with oxygen and hydrogen. Common examples include sulfuric acid (H2SO4), nitric acid (HNO3), and phosphoric acid (H3PO4). These compounds are named based on the nonmetal element present in the compound.
Chlorine's mass number is 35.5. This is an average value due to the presence of two isotopes of chlorine, chlorine-35 and chlorine-37, in nature.
Free Chlorine is the Chlorine which is free to do its work in the pool, as opposed to Combined Chlorine which is chlorine that has combined with contaminants and is tied up and ineffective as a sanitizer in the pool. Sometimes you will see it abbreviated as FAC, which stands for Free Available Chlorine.
Total Chlorine = Free Chlorine + Combined Chlorineor, put another wayTotal Chlorine - Free Chlorine = Combined ChlorineFree Chlorine is the chlorine that is doing its job.Combined Chlorine is the chlorine that has combined with contaminants such as nitrogen. It is ineffective as a sanitizer and it is noxious.Total Chlorine is the total of these two levels.To eliminate the Combined Chlorine (making all the chlorine in the pool Free Chlorine) you must shock the pool to remove the contaminants. You must reach "Breakpoint Chlorination", which is the addition of chlorine to your pool equivalent to the Combined Chlorine level times 10.example:Total Chlorine = 1.5ppmFree Chlorine = 1.0ppmSo, the Combined Chlorine (the difference between the two tests) is .5ppmBreakpoint chlorination, in this example would be .5ppm X 10 = 5ppm. So, in this example, you would add enough chlorine to your pool to raise the chlorine level up by 5 parts per million.
Fluorine can not form oxyacids because fluorine is more electronegative than oxygen, and oxyacids are formed only from elements that are less electronegative than oxygen.
aluminium is passive towards oxyacids due to formation of protevtive layer of oxide. this protective layer resists the contact of aluminium with water or oxygen thatswhy aluminium is passive towards oxyacids
No HCl is not an oxyacid like Nitric acid or sulfuric acid
Oxyacids of iodine are:- iodic acid: HIO3- iodous acid: HIO2- hypoiodous acid: HIO- ortho periodic acid: HIO4- meta periodic acid: H5IO6

in my opinion flourine is very electronegative and it cannot exist in positive oxidation states in its compounds .in oxyacids of halogens ,oxygen carries a negative charge while the halogen carries a positive charge.the electronegativity of flourine is 4,while that of oxygen is 3.5. so due to high value of electronegativity ,flourine shows reluctance to form positive oxidation states and donot form oxyacids........
H2 and a polyatomic ion e.g.) H2CO3 (carbonic acid) hope that helps:)
Chlorine is number 17 in the periodic table, so using the electron shell arrangement,2:8:7:It has 7 electrons in its valance shell so its charge becomes Cl7+ when these 7 electrons are 'donated' (= lost to, as reductant) to oxygen (only in oxyacid or salt perchlorate).Other valence values are +5, +3 and +1 in oxyacids: chlorate, chlorite and hypochlorite, respectively.
