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
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 0.10 M HCl solution?
The pH of a 0.10 M HCl solution is approximately 1.0. This is because HCl is a strong acid that ionizes completely in water to form H+ ions, resulting in a high concentration of H+ ions in solution and a low pH.
Why does adding 6 M HCl to the yellow solution of methyl red tend to cause the color change to red?
Adding 6 M HCl (hydrochloric acid) lowers the solution's pH, causing a shift in methyl red's equilibrium towards the red form. This is because methyl red is a pH indicator that changes color from yellow (at a higher pH) to red (at a lower pH). The addition of acid protonates the indicator, resulting in the color change.
What is the pH of 200 mL of 0.002 M HCl?
The pH of 0.002 M HCl is approximately 2.3 assuming complete dissociation of HCl into H+ and Cl- ions. The calculation involves taking the negative base 10 logarithm of the concentration of H+ ions which is given by the molarity of the acid solution.
The pH of a 0.1 molar aqueous solution of HCl would equal -?
The pH of a 0.1 molar aqueous solution of HCl would be 1. This is because HCl is a strong acid that completely dissociates in water to produce H+ ions, resulting in a high concentration of H+ ions in solution, leading to a low pH value.
What is the pH of a 0.00001 molar HCl solution A 1 B 9 C 5 D 4?
The pH of a 0.00001 molar HCl solution is 5. HCl is a strong acid, and at this concentration, it would dissociate almost completely in water to produce H+ ions, resulting in a pH of 5.
How can you prepare several different pH solutions from a 1 Molar stock solution of HCl?
To prepare several different pH solutions from a 1 Molar stock solution of HCl, you can dilute the stock solution with water to achieve the desired pH. You can use a pH meter to measure and adjust the pH as needed by adding either more stock solution or more water. Make sure to handle HCl with caution as it is a strong acid.
What is the pH of a 6M HCl solution?
The pH of a 6M HCl solution is 0.
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.
What is the pH of a solution containing 6M HCl?
The pH of a solution containing 6M HCl is 0.
What is the pH of a 1.0x10-4m hcl solution?
- log(0.00450 M HCl)= 2.3 pH=======
What is the pH of an aqueous solution of HCl with a concentration of 42m?
The pH of a 42m HCl solution would be approximately -log(42) = -1.62. This solution is strongly acidic.
What is the pH of 0.0001M aqueous solution of hcl?
The pH of a 0.0001M aqueous solution of HCl is 4. The pH of a solution is calculated using the formula pH = -log[H+], where [H+] is the concentration of hydrogen ions in the solution. Since HCl is a strong acid that dissociates completely in water, the concentration of H+ ions in a 0.0001M solution of HCl is also 0.0001M.
What is the pH of a 0.001 M of HCl solution?
its PH is 3
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.
What is the pH of a solution of 0.010 M HCl?
The pH of a 0.010 M HCl solution is approximately 2. This is because HCl is a strong acid that completely dissociates in water to form H+ ions, resulting in an acidic solution.
