Answer:
pH = 5.76
Explanation:
We can solve this problem by using<em> Henderson-Hasselbach's equation</em>:
pH = pKa + log![\frac{[SodiumAcetate]}{[AceticAcid]}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BSodiumAcetate%5D%7D%7B%5BAceticAcid%5D%7D)
We are already know all the required information, thus we<u> input the data given by the problem</u>:
pH = 4.76 + log(20/2)
And finally <u>calculate the pH</u>:
pH = 5.76
The pH of that acetic acid solution is 5.76.
Answer:
Three ways that I would make most of this situation are going near an area to avoid the things drifting into space. I would seek shelter in a basement. I would also stay indoors.
Earth's atmosphere and its oceans, rivers, and lakes would be one of the first things to drift away into space, we would need to avoid those obstacles by seeking shelter. The first problem is that Earth is rotating at high speed, rather like the way a weight on a string rotates if you spin it around your head. Anyone unfortunate enough to be outside at the time would quickly be lost. People inside buildings would be safer because most buildings are so firmly rooted to the ground that they would stay put even without gravity – at least for a while.
Answer:
The PH of the mixture is 4.74
Explanation:
The number of millimoles of acetic acid is calculated using the formula:
No of millimoles= Molarity * Volume( in ml)
= 0.25M * 30ml = 7.5 moles
Number of millimoles of KOH is calculated using:
Number of millimoles = Molarity * Volume ( in ml)
=0.05M * 75ml
= 3.75 moles
The PH of the solution is derived using:
pH = pKa + log [salt] / acid
= ![-log [ 1.8 * 10^5 ] + log [ 3.75 mmoles/ 3.75 mmoles]](https://tex.z-dn.net/?f=%20-log%20%5B%201.8%20%2A%2010%5E5%20%5D%20%2B%20log%20%5B%203.75%20mmoles%2F%203.75%20mmoles%5D%20)
=4.74
I would help if i could im sorry im sure someone else will answer soon im honestly trying to help as many people as i can
All of the above
hope this helps!
