What is the pH of a 0.20 M HCl solution?
Answer: HCl is a strong acid, it dissociates 100% (I.e. completely): (HCl)F = 0.020 M = (H3O+) So, pH = – log (H3O+) = -log (HCl)F = -log(. 020)=1.70 Voila!

What is the pH of a 0.040 M aqueous solution of HCl?
4.70 of pap-HCl. 11. A 0.040 M solution of a weak acid (call it HA) has a pH of 4.70.
How do I calculate pH?
To calculate the pH of an aqueous solution you need to know the concentration of the hydronium ion in moles per liter (molarity). The pH is then calculated using the expression: pH = – log (H3O+).
What is the pH of a 0.010 M HCl solution?
pH = 2 A 0.010 M solution of hydrochloric acid, HCl, has a molarity of 0.010 M. This means that (H+) = 1 x 10-2 M. The pH of this aqueous solution of H+ ions is pH = 2. You will notice that the pH number is just the positive exponent of 10 from the Molar concentration.
What is the pH of 0.0015 M of HCl?
Therefore, (HCl)=(H+) , and (H+)=0.015 M at equilibrium. Plug this into your calculator, and the answer will be 1.82 , with significant figures (note that the digit 1 in the answer does not count as a significant figure. If you need help with significant figures and pH, please leave a comment.) I hope that helps!
What is the pH of a 0.010 M solution of HCl?
pH = 2 A 0.010 M solution of hydrochloric acid, HCl, has a molarity of 0.010 M. This means that (H+) = 1 x 10-2 M. The pH of this aqueous solution of H+ ions is pH = 2.
What is the pH of a 0.45 M solution of hydrochloric acid HCl?
The pH is 1.60.
What is the pH of a 0.10 M solution of HCl?
In this problem, a 10 – 10 M solution of HCl contributes 10 – 10 M (H +). The ionization of water contributes 10 – 7 M (H +). The effective (H +) of this solution is 10 – 7 M and the pH=7.
What is pH formula?
∙ The formula for calculating pH is pH=−log(H3O+) ∙pH is the negative logarithm (to base 10) of the molar hydronium ion concentration. ∙ pH+pOH = 14 always.
What is the pH of a 0.00805 M solution of HCl?
The pH of the hydrochloric acid solution is 2.10.

What is the pH of a 0.040 M HCl solution?
4.70 of pap-HCl. 11. A 0.040 M solution of a weak acid (call it HA) has a pH of 4.70.
What is the pH of a solution with 0.025 M of HCl?
0.025 M HCl solution has a pH of −log(0. 025)=1. 60.
What is the pH of 0.1 M HCl solution?
Assuming complete ionization, the pH of 0.1 M, HCl is 1.
How do you find the pH of 0.1 M HCl?
HCl is a strong acid which dissociates completely to form H+ and Cl- ions. 0.1 molar HCl will dissociate to form 0.1 molar H+ and Cl- ions. So pH = -log(0.1) which is equal to 1. So the answer is 1.
What is the pH of 0.0015 m of HCl?
Therefore, (HCl)=(H+) , and (H+)=0.015 M at equilibrium. Plug this into your calculator, and the answer will be 1.82 , with significant figures (note that the digit 1 in the answer does not count as a significant figure. If you need help with significant figures and pH, please leave a comment.) I hope that helps!

Thus, we obtained that pH of the 1M solution of HCl is 0. So, the correct answer is (A).
How do you calculate pH of a solution?
To calculate the pH of an aqueous solution you need to know the concentration of the hydronium ion in moles per liter (molarity). The pH is then calculated using the expression: pH = – log (H3O+).
