HCl is a strong acid, therefore we can assume that it ionises completely into H+ (or H3O+ if you prefer) and Cl- ions.
Therefore an 0.10 M HCl solution will contain 0.10 moles/L of H+ ions.
pH = -log10[H+] where [ ] denotes "concentration of" in moles/L
Note that the formal definition of pH relies on the "activity" of H+ (which is the product of an activity coefficient and concentration), but for simple problems this can be be ignored.
So pH = -log[0.1]
= 1.0

What is the pH of a 0.280 molar HCl solution?
The pH of a 0.280 M HCl solution is approximately 0.55. This is because HCl is a strong acid that dissociates completely in solution to produce H+ ions, leading to a low pH value.
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 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 a 4.3 x 10-2 M HCl is the solution?
p(x)=-log([x])So... pH=-log([H+])pH = 1.4
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 a 6M HCl solution?
The pH of a 6M HCl solution is 0.
How to calculate pH of 1N HCl solution?
The pH of a 1N HCl solution can be calculated using the formula pH = -log[H+], where [H+] is the concentration of H+ ions in the solution. For a 1N solution of HCl, the concentration of H+ ions will be 1M, so the pH will be -log(1) = 0.
What is the pH of a solution containing 6M HCl?
The pH of a solution containing 6M HCl is 0.
What will be the pH of the solution formed by mixing 40ml of 0.1M HCl with 10ml of 0.45M NaOH?
To calculate the pH of the resulting solution when mixing HCl and NaOH, you need to determine the moles of each reactant. Use these values to find the limiting reagent and the excess reagent. Then, calculate the concentration of the excess reagent left in solution. Finally, use the concentrations of the excess reagent and water to determine the pH of the resulting solution.
.45g of hydrochloric acid is dissolved in water to make 3.5l of solution what is the pH of HCl?
The pH of a solution of HCl is calculated using the concentration of H+ ions. Since HCl dissociates completely in water, the concentration of H+ ions is equal to the concentration of HCl. First, calculate the concentration of HCl in the solution: 0.45g HCl / (36.46 g/mol) = 0.012 mol HCl. Then, divide the moles of HCl by the volume of the solution in liters to get the concentration in mol/L. Finally, calculate the pH using the formula pH = -log[H+].
How do you calculate the pH of a solution of 0.001 mol dm HC1?
To calculate the pH of a 0.001 mol/dm³ HCl solution, you use the formula pH = -log[H+]. For HCl, since it is a strong acid, it dissociates completely into H⁺ ions. Thus, the concentration of H⁺ ions in a 0.001 mol/dm³ HCl solution is also 0.001 mol/dm³. Taking the negative logarithm of 0.001 gives a pH of 3.
What is the pH of a 1.0x10-4m hcl solution?
- log(0.00450 M HCl)= 2.3 pH=======
How calculate pH for a solution?
HCl is a strong acid and dissociates completely. Therefore it can be found using the equation: ph= -log [H+]
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 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.
Calculate the molarity of HCl of pH 5.7?
To calculate the molarity of a solution from its pH, use the formula: pH = -log[H+]. In this case, pH 5.7 corresponds to [H+] = 1 x 10^-5.7 M. Given that HCl is a strong acid and dissociates completely in water, the molarity of HCl is also 1 x 10^-5.7 M.
What is the pH of a 0.280 molar HCl solution?
The pH of a 0.280 M HCl solution is approximately 0.55. This is because HCl is a strong acid that dissociates completely in solution to produce H+ ions, leading to a low pH value.
