A 0.361 molar solution of the weak acid HA with a pKa of 4.039 is titrated with a 0.163 molar solution of NaOH. What is the pH of the solution at the equivalence point of this titration?

You need to know the volume of the weak acid being titrated so you can find how many moles of base are needed to match that of the acid.

How do you calculate molarity for milli molar and nano molar solution?
The term molar it refers a form to know the concentration of a solution, and it is equivalent to a molar unit in a litre of solvent 1 Molar (1M) = 1 mole (molecular weight from the structure you are interested in) / 1000 mL or 1 L. Milimolar is the thousandth part from a solution 1M
How is a 5 molar solution different than a 1 molar solution of koolaid?
They're actually exactly the same in that neither of them exists.
What is the molar solution?
When we say that a solution has a given molarity, it tells you how much of a given substance is dissolved into the solution. A 1.0 molar solution has one mole of a substance dissolved into one liter of water.
What is a 1 molar solution?
Molar solution, commonly called molarity, is the amount of amount of substance in a certain volume. Typically it is measured in moles per litre. A 1 molar solution means there is one mole of substance per one litre. This can also be called a one mole concentration of solution.
How can you measure the molar heat of solution of solids?
You die.
20 ml of acetic acid is titrated with a solution of 0.15 M NaOH If 35 ml of NaOH are required to reach the equivalence point what is the concentration of the acetic acid solution?
0.01 molar
How do prepair normal solution of any chemical?
Normal concentration is the ratio between molar concentration and an equivalence factor.
What is hypothesis of a acid base titration?
to determine the concentration of the unknown solution and to determine the molar concentration of acetic acid in a sample of vinegar by titrating it with a standard solution of NaOH.
How do you solve this titration question?
Titration equation can be solved by following the steps below: 1. write a well balanced equation. 2. Calculate number of moles of standard solution that is in the solution. 3. User molar relationship to convert moles of standard solution to that of unknown solution. 4. Find the number of moles of unknown solution.
A 25.00 mL sample of HBr is titrated with 0.150 M standardized sodium hydoxide solution the endpoint was reached when 18.80 mL of titrant had been added calculate the molar concentration of the HBr?
(25.00ml HBr)( Molarity ) = ( 18.80ml NaOH )( 0.150 M ) Molar concetration of HBr = 0.108 M

What is the molar mass of a solution containing 2000 grams?
Only a compound has a molar mass not a solution.
How do you standardize a solution of NaOH and what reagents to be used?
If you have a standard solution of an acid, like hydrochloric or sulfuric, you can perform a titration in the presence of phenolphtalein or methyl orange and calculate the solution's normality or, you can weigh a sample of a strong solid acid ( orthoiperiodic acid or even oxalic acid), titrate the acid with the hydroxide solution, again in the presence of phenolphtalein or methyl orange and calculate the concentration of NaOH. If you want to have a solution with an exact concentration, let's say 1 molar, and the actual concentration is 1,33 molar, you simply calculate how much water you need to ad in a specific quantity of solution, to dilute it to exactly 1 molar.
How should the pH of a 0.1 molar solution of nac2h3o2 compare with that of a 0.1 molar solution of kc2h3o2?
the PH will be the same
40.00 mL of 0.10 M HC2H3O2 is titrated with 0.15 M of NaOH. Ka of HC2H3O2 is 1.8x10-5 What volume of NaOH is used to reach equivalence pt and what molar concentration of C2H3O2- equivalence pt?
40.00(mL)*0.10(M) = VNaOH(mL)*0.15(M) , soVNaOH(mL) = 40.00*0.10 / 0.15 = 26.67 = 27 mLCacetate = 0.10 * [ 40.00 / (40 mL + 26.7 mL) ] = 0.060 MMark: nothing to do with Kacid !
How do you make a 0.1 molar solution if you had a 1.0 molar solution to start with?
100 mL of solution 1 M mixed with 900 mL distilled water
