Yeah, this virus sucks.

Thanks for putting the formulas up! You're really good at filtering the extra info that might give context for more advanced students but easily confuses beginner students. I come to your channel to get a fundamental breakdown of my 2 hour lectures lol. So thank you!!

i dont know what i would do without you melissa, when i get my degree i wish i can thank you in person. your literally my tutor

oh my gosh. THANK YOU. I've been staring at my textbook for hours over this and haven't been able to sort out which formula gives you what- the summary at the end was a LIFESAVER!

You literally make the coolest videos ever. You taught me more in 5 minutes than my teacher could in 2 hours. Thanks!

I've been struggling learning this for weeks and now I learned them in 4 minutes. You are awesome ❣️

The pOH, pH, H+ and OH- concentration conversions are at 3:04 You're so clutch for this!

This was so helpful! 💗 I love how you explain it step by step in a simple way. My chemistry teacher can be a all over the place sometimes. 😅

you. are. a. life. saver. Thank you so much! I barely understood the lesson in my chemistry class, but you explained it in a much detailed and better way. This will be on my final so this definitely helped!

You're an angel for helping us chemistry students. Thank you

Your amazing! I'm going to use this on my test! Thank you!

THANK YOU SO MUCH ! I DIDNT UNDERSTAND WHEN THE TEACHER EXPLAINED IT BUT NOW I DO

Thank you so much. You are so much easy to understand than my teacher. I passed the final, thanks to you!

This video helped me understand the formula so much!

Even before watching any of your videos I make sure to hit the like button because I usually forget to do it when I click on your next video

I don't know why you don't have 50 mil subscribers because you are actually the best tutor out there. All the other tutors are so complex and you just get right to the point.

why if I calculate 10^(-10.61) it shows 24.55 but on your solution it shows 2.5 is there something wrong about my calculator?

Thanks, I haven't made a video on this yet, and I needed to share one with my students. Going through all the youtube pH videos, this was the only one that was both correct and understandable.

test in three hours your a life saver

minute 2:36, How do you do the division of 1x10-14/3.1x10-9? I thought yo had to subtract the coefficients? I must be doing something wrong I get -5 not -6. Please help Melissa. PS thank you so much for all this work. Wait a second I got it, it is the rounding, I was using 3.1 not 3. Got it

How many times stronger is the hydrogen ion concentration of pH 4 solution as compared with a pH 9 solution

May I ask some question, Suppose if we have hydrolysis ammonia NH4+ NH3 + H+ Kh = [NH3][H+]/[NH4] = 10^-9 mol/L To 1 liter of pure water, 1mmol of ammonium chloride was dissolved, and pH was adjusted to 9 using sodium hydroxide. What will be the concentrations of ammonium ion and free ammonia?

Awesome 👌

Hello! This was a really helpful video. I'm currently in chemistry Higher Level in the IB system and we are learning about weak acid and base dissociation constants (ka, kb, pKa, pKb) and their calculations and I was wondering if you had a video about that or if you can make one as I'm finding them rather difficult.

You make things easier.... Can you make a video on molecular orbital diagram please 😢🙏🙏. You make me understand

This helped sm

I have not done calculations like this in a number of years and it would be really helpful if someone would step through exactly what you select on your graphing calculator and also going the reverse; if I have the [OH-], then what do I plug in to get to [H+].

Whats the formula for ( H subscrip 2 O positive) ?

This is not fair! Some people wrote in the comments that they watched this video before they entered the university finals. And the problem is that I have to learn this as a high school student in Turkey. Moreover, this is known as one of the easiest subjects! It wears me out that I can't even go to university without knowing these chemical calculations.

Can u explain further how’d you find the pH 3.39?

Finals are coming up and your videos, along with the step by step notes I purchased, have definitely helped me feel more confident about these exams! Going to put all of this to use tomorrow, Thanks Melissa! Hopefully I pass because I need to graduate in 2 1/2 weeks lol
