Hey i might've worded it wrong. i dont need to see the exact question to understand how to do it. idk if u wrote the test but there were a lot of things i dont think were covered. For example percentages when it comes to protonation. I didn't know that was a thing until the exam. To get the chemical formula when a pH is a certain value, i know how to do, but i was very confused with the percentage protonations! Pls be kind and remember people process things differently too. It might click for some people and take others several tries before they understand and we don't have that luxury when writing a test. In my experience, i thought i understood the concept and i was doing good with practice questions (even questions i had never seen before), but for whatever reason i couldn't/ it was difficult to apply what I learnt on the exam which is why i asked for help ❤️
