The Ka of an unknown weak acid is 5.4 x 10 to the power of negative 10. Determine the pKa of the weak acid?
pKa = -log KapKa = -log 5.4x10^-10pKa = 9.27
How can you calculate pka valve if pH is given?
How can you calculate pka valve if ph is given?
What is the Ka for aspirin with a pka of 3.48?
All you need to do to get Ka is to take the antilog of the pKa.
How you can select buffer in hplc according to pka value?
By following + or - 2 pH to the pKa value
What is pKa in chemistry?
It refers to the acidity of the fatty acid (which make up the oils). Every fatty acid is composed of a non-polar long chain of hydrocarbons (carbon and hydrogen) and a polar head made up of Carboxylic ACID. Every acid has something called pKa which determines the acidity of that acid.The bigger the pKa (e.g. 25), the weaker the acid.The smaller ther pKa (e.g. 2), the stronger the acid.
Is it true that the sum of pka and pkb is always equal to 14 at all temperature for any acid?
No it is not true because value of pkw changes with change of temperature. It's value is 14 at 250C and less at high temperature
What is Pka for normal water in room temperature?
If you are asking about the acidity of water under normal conditions, its pKa is 15.74.
What is pka value for sodium bicarbonate?
There are two answers: bicarbonate has two pKa's - because bicarbonate can gain a proton to become carbonic acid or lose a proton to become carbonate. Two reactions; two pKa's. The pKa for bicarbonate carbonic acid reaction is 6.4 The pKa for bicarbonate carbonate reaction is 10.3 Both pKa's are temperature sensitive.

It is around pKa=13
What is the pka value of Doxofylline?
Doxofylline Pka value is about 9.8.
What is the advantage of knowing the pKa of an acid-base indicator?
The advantage of knowing the pKa of an acid-base indicator is that it tells you the approximate pH value at which the color of the indicator changes. For example, if the pKa of an indicator is 5, then it means that it's going to change colors at around pH 5.

The pKa of sulfonic acid is < 0
