The pH in aqueous solution of hcl at 25c is 4 hcl0.003 moles was added to 1l of this solution calculate the new pH in the solution assume complete dissociation of hcl?
if its complete dissociation, then the products would be a salt and water, which means the pH is 7 or neutral. OMG, if the pH is currently 4 then [H+] = 1.0 e-4 M (pH = -log[H+]) if you add 0.003 moles then 1.0e-4 M +.003 M = .0031 M (Since the strong acid HCL completely dissociates in aq solution) pH = -log [.0031M] = 2.51
Calculate the pH of a 0.01M solution of sodium acetate?
0.1 molar solution around 8.9 at 25C Per Merck Index...
What is the pH of a 4.3 x 10-2 M HCl is the solution?
p(x)=-log([x])So... pH=-log([H+])pH = 1.4
What is acidity of hydrogen chloride?
Hydrogen chloride is an acid and its acidity depends on the concentration of the solution. For example, a 0.1M solution of HCl has a pH value of 2.0
What is the pH number of sodium hydroxide?
Sodium hydroxide does not have a pH number. The pH of a solution of sodium hydroxide depends entirely on the concentration of it in that solution. To learn how to determine the pH of a sodium hydroxide solution, see the Related Questions links.
The pH of a 0.1 molar aqueous solution of HCl would equal -?
1
How is the pH of the solution calculated?
The pH scale is a convenient method for expressing the hydronium ion concentration of a solution. pH = log(1/[H+]) = -log [H+]. [H+] is the hydronium ion concentration in M (molarity), which is the number of moles of solute per liter of solution.
How can you prepare several different pH solutions from a 1 Molar stock solution of HCl?
dilute your HCl solution to 0.2 M HCl solution and then follow above mentioned link : http://delloyd.50megs.com/moreinfo/buffers2.html
What is the pH of a 0.00001 molar HCl solution A 1 B 9 C 5 D 4?
C. 5
Can an aqueous solution have a pH of zero?
No. pH is a log scale. You can't have a pH of zero. ---- Above answer left in to correct a misconception. Yes, you certainly can have a pH of zero. A 1 molar solution of a strong acid has a pH of zero, and stock HCl (roughly 12 molar) has a pH of about -1.1 or so. pH is the negative log of the hydrogen/hydronium ion concentration, which for a strong acid is approximately the same as the acid concentration. The log of 1 is zero, therefore the pH of a 1 molar solution of a strong acid is zero. The log of 10 is 1, therefore the pH of a 10 molar solution of a strong acid is -1.
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
The pH of a 0.01 M solution of HCl in water would be?
pH = - log[H+] so a 0.01 M solution of HCl has, pH= 2
What is the pH of a 0.001 M of HCl solution?
its PH is 3
Is there a molar mass of 4.0 PH buffer?
Ph gives the hint about the proton gradient of the solution as pH=-log[H+] we need the inforamtion of the molecular composition of the solution to know about the molar mass. Ph gives the hint about the proton gradient of the solution as pH=-log[H+] we need the inforamtion of the molecular composition of the solution to know about the molar mass.
What is the pH of a solution of 0.010 M HCl?
Its pH value is 2.
What is the pH of a 1.0x10-4m hcl solution?
- log(0.00450 M HCl)= 2.3 pH=======
What is the pH of 10.0L of 0.0020 M HCL?
0.002M HCl means 0.002 moles HCl in 1L solution. Therefore 0.02 moles HCl in 10L solution. pH = 2-log2 = 2-0.3010 = 1.6990
