This equation relates the pH, the ionization constant of a weak acid, and the concentrations of the weak conjugate acid-base pair in a buffered solution. Scientists often use this expression, called the Henderson-Hasselbalch equation, to calculate the pH of buffer solutions. It is important to ...
Calculating pH «on:July 24, 2009, 10:49:04 PM » Maybe this is too advanced for High School chemistry, but I'm curious.. How do you calculate the pH of a solution? I saw the formula -log[H+] What is H+? Could someone show me a couple of examples, first with HCl, then ...
The ionization-constant expression for a solution of a weak acid can be written as:Rearranging to solve for [H3O+] yields:Taking the negative logarithm of both sides of this equation giveswhich can be written aswhere pKa is the negative of the logarithm
Calcaulte hte pH of a .20M aqueous solution of (CH3)2NH2C2H3O2, dimethylamine acetate. Here's what I did: (CH3)2NH2C2H3O2--> (CH3)2NH2++ C2H3O2-. Since acetate doesn't do anything to the pH I take it out of the equation so I have ...
pH values between 7.3-8.5 containing phosphate enol type pyruvate, phosphoenolpyruvate carboxylase, NADH, malate dehydrogenase at a temperature between of 30-37 degree C, after incubation, detecting A1 at 380 nm location; 3) adding the reaction solution of step 1) into the solution of step 2),...
Is one better than the other? Aging Report SQL Query Alias all columns in a given table Alias column with variable value in SQL Script All MonthNames and Month numbers in sql server All queries combined using a UNION, INTERSECT or EXCEPT operator must have an equal number of expressions in ...
Okay, so I have a quick question about a problem in my lab. The question is: Calculate the number or moles of atoms of magnesium ribbon used. Now there is just too many "of"s in that sentence for me. Now this maybe a stupid question, but what is the question asking exactly? What...
SUBSTANCE: method of locating a pointer in a circular buffer involves the following steps: the length, initial and final address of the circular buffer are established; the position of the current address pointer in the circular buffer is determined, a base mask is created, a shift mask is ...
