in this video, we're gonna take a look at Oxy acids strength. So we're gonna say here that the strength of Oxy acids is based on the number off oxygen's or the electro negativity of the nonmetal. We're gonna go over. When do we look at either one? So here we're gonna say the rule is the number one rule for oxy acids is if my oxy acid has two or more oxygen's than hydrogen zones, then my oxy acid is a strong acid. So if we take a look at the first one we have here h n 03 we're gonna say it's an oxy acid because it contains hydrogen, a non metal and an oxygen. Here, the number of oxygen's is three. The number of hydrogen is just one. When we subtract them, we have to oxygen's remaining. You must have a minimum of two oxygen's remaining in order to be considered a strong oxy acid. Here, it meets that requirement, so it's strong. Next one, we have fennel, so C six h five h here it has one oxygen and then it has five plus one more. That's six hydrogen. So in this one, we don't have any oxygen's remaining. Remember, we need a minimum off to oxygen's remaining to be considered a strong oxy acid, so this one doesn't meet the requirements. So it's weak. Then here we have purple MK acid. So here we have four Oxygen's. We have one hydrogen, so we have three oxygen's remaining. So we've met the minimum requirement of having at least two oxygen's left, so this one would be strong. So when it comes to Oxy acids, this is the first rule that you need to remember. You need to have a minimum of at least two more oxygen's than hydrogen to be considered a strong oxy acid. We're gonna move on to the next portion when we talk about this topic of oxy acids. But keep in mind this first important role
