Consider the titration of 30.0 ml of 0.030 M NH3 with 0.025 M HCl the equivalence point is reached when 36 ml of HCl titrant is added what is the pH at the equivalence point?
pH = 5.56 at 36.0 ml(equivalence point)
How do you prepare 0.5M Tris-HCL pH 7.2?
for 1L 121.1 gr tris base 80 ml HcL 920 ml Distilled Water
What is the pH of a 0.100 molar HCl solution?
The answer depends on several unspecified variables, most importantly the final molarity of the solution, which depends on the final volume. You can calculate the value yourself using the formula: pH = -log[H+] where [H+] is the final concentration of H+ ions in solution. For HCl, [H+] is equal to molarity. So, for example, if you add 50.0 ml of 1.0M HCl to 950 ml of deionized water, your final concentation is: (50.0 ml/1000 ml) * (1.0M) = 0.05M Therefore: pH = -log[0.05] = 1.3
What is the pH of Na2HPO4?
For example, to obtain a solution with the pH=7,00 mix: 756 mL 0,1 M solution of Na2HPO4 with 244 mL of 0,1 M HCl solution.
Is pH a extensive or intensive property?
pH is an INTENSIVE property as it does not depend on the amount of material present. The pH of 1 ml of solution x is the same as the pH of 100 ml of solution x.
Calculate the pH of a solution prepared by diluting 3.0 mL of 2.5 M HCl to a final volume of 100 mL with H2O?
Because HCl is a strong acid, it dissociates completely to H + Cl. Therefore, 3.0 mL x 2.5 M HCl = 7.5 meq of H+ . In 100 mL of solution, this is 0.075 M H+. pH= - log [H] = - log (0.075) = - (-1.1) = 1.1 (two significant figures)
What is the pH of 200 mL of 0.002 M HCl?

What is the pH of .25M HCl?
- log(0.25 M HCl) = 0.6 pH ------------
What is the pH of a 1.0x10-4m hcl solution?
- log(0.00450 M HCl)= 2.3 pH=======
What is the pH of the solution formed when 100 milliliter of hcl is mixed with 100 milliliter of NaOH?
I think it'd be pH 7. Same amount of both, providing they are the same molarity!
If you make up a solution of 100 mL of 0.1 M HEPES in the basic form what will be the pH?
pH is 9.75
