Rank the following oxyacids in terms of increasing acidity. a) HClO 3 b) HBrO 4 c) HBrO 3 d) HClO 4

Well here we need to rank the following oxy acids in terms of increasing acidity. So we're gonna go from weakest oxy acid, the strongest oxy acid. Remember when it comes to oxy acids, what we need to do first is figure out how many oxygen we have left for each. So all you're doing is you're subtracting the number of oxygen's by the number of hydrogen to see how many you have left of each one. So this one will give us two oxygen's left. This one will be three oxygen's left, two oxygen's left and three oxygen's left again. We know that A and C. Are the are the weaker of the two of the four because they have less oxygen remaining. Remember when the number of oxygen's are the same. We look at the electro negativity of the nonmetal Chlorine is more electro negative. So therefore eight Cielo 3 will be more acidic. So we're gonna start out with hbR 03 is the weakest than H. C. L. 03. Now we have hbr oh four and H C. L. 04 again the number of oxygen remaining is the same. So we go back to looking at the electro negativity of the nonmetal again, chlorine is more electro negative than bro me. So H B. R. 04 would be next and then H. C. L. 04 which is per caloric acid is the strongest oxy acid that we have here. So remember first look at how many oxygen's you have remaining. Whoever has more remaining is stronger. But then if they're the same number remaining. Look at the electro negativity of the nonmetal.

Verified step by step guidance

Identify the oxyacids given: HClO3, HBrO4, HBrO3, and HClO4.

Understand that the acidity of oxyacids generally increases with the number of oxygen atoms bonded to the central atom, as more oxygen atoms can stabilize the negative charge on the conjugate base through resonance.

Compare the number of oxygen atoms in each oxyacid: HClO3 has 3 oxygens, HBrO4 has 4 oxygens, HBrO3 has 3 oxygens, and HClO4 has 4 oxygens.

Recognize that for oxyacids with the same number of oxygen atoms, the acidity increases with the electronegativity of the central atom. Chlorine is more electronegative than bromine.

Rank the oxyacids based on the number of oxygen atoms and the electronegativity of the central atom: HBrO3 < HClO3 < HBrO4 < HClO4.
