pka = ph - A-A1/A2-A. but i dont understand what numbers i need to put as A; A1 ; A2. i know that A is the negative log of T but still i dont understand it. i tried to find info on the beer Lambert law but all the info i found doesn't connect to chemistry only to phy...
The Henderson-Hasselbalch equation gives the relationship between the pH of an acidic solution and the dissociation constant of the acid: pH = pKa + log ([A-]/[HA]), where [HA] is the concentration of the original acid and [A-] is its conjugate base. At the equivalence point, enough ...
How do you find pKa from a titration curve? How to choose an indicator for an acid-base titration? How do you calculate water hardness using EDTA titration? Why do we heat oxalic acid before titration? What is the endpoint of titration?
Ka values can be easily looked up online, and you can find the pKa using the same operation as for pH if it is not listed as well.Online pH and pOH calculator See the Resources for a web tool that allows you to determine the pH of various acidic and basic solutions. You can use ...
These new mols are used to find the pH. What equation is used for calculating the pH of an acid buffer? To calculate the pH of an acid buffer, the Henderson-Hasselbalch equation is used, which is pH = pKa + log(acid/base). The acid's concentration is on top of the fraction, and...
Any mechanism must account for the fact that the Qi-site operates as an interface between the 1-electron chemistry of the b-heme chain, and the 2-electron chemistry of the quinone pool, and involves intermediate states tuned to binding of the three components of quinone redox chemistry, Q, ...
21.Combine 10.0 mL of your weak acid solution in flask 1 with 10.0 mL of the conjugate base solution in flask 2, mix, and measure the pH and record. This is the pKa of the acid. 22.Your teacher will assign you the pH of a buffer to prepare. Calculate the volume of weak acid and...
Explain the chemistry behind this. I need help with this problem: How many chiral centers does this compound have? (The answer should be 4) But I don`t understand how to find them. Can someone please show me which of the C-atoms that Explain why ...
When pKa is a whole number, such as -7, this operation is easy to perform, but when it contains a fraction, such as 7.5, you may have to look up the value in a table. You can also find it on a scientific calculator by inputting the number and pressing the exponent key, which ei...
