A 500.0-mL buffer solution is 0.100 M in HNO₂ and 0.150 M in KNO₂. Determine if each addition would exceed the capacity of the buffer to neutralize it. c. 1.25 g HBr

five or interact with the addition of 2.56 g of Hydrofluoric acid exceeds the capacity. The 250 million births solution That is 0.125 moller of hydrogen fluoride, 0.175 moller studying fluoride. You know that Hydrofluoric acid is an acid. It's gonna consume the conjugate base and it will exceed hit. The malls of hydrochloric acid is greater than the malls of sodium fluoride. We need to calculate the malls of each Have 2. grams clark acid. And in one bowl have the molar mass. This is 1.008g. R 35 .453g. We're gonna get 36.46 g. We get 0.0702 walls of hydrochloric acid. And we know that polarity was more than that wanted by leaders of the solution. I need to convert our volume into leaders 250 million years And in one liter of 1000 ml You get 0.25 leaders Number was 0.175 miles studying fluoride and one leader We have 0.25 leaders. Just give us 0.04 37 5 malls. So this number is less than the moles of hydrochloric acid. Yes, it will exceed the buffer capacity. Thanks for watching my video and I hope it was helpful
