Is HClO4 a strong acid?
The 7 common strong acids are: HCl, HBr, HI, HNO3, HClO3, HClO4 and H2SO4 (1st proton only).
Remember what we mean by a weak acid or weak base.
They simply do not ionize completely whereas a strong acid or base does..
What is the pH of dilute hydrochloric acid?
pH of dilute HCI is found to be 2 and pH of dilute NaOH is 14. Solutions with pH = 0 to 3 are strongly acidic, so dilute HCI is a strong acid….CBSE Class 10 Science Lab Manual – pH of Samples.pH4ColourOrangepH9ColourBluepH144 more columns•Jan 31, 2018
Is 1m HCl dangerous?
If you have to ask this question, you are clearly not a chemist and therefore a 1 molar solution of HCl is dangerous to you. Do not drink it. Do not wash you face in it.

Is the pH scale?
The pH scale measures how acidic or basic a substance is. The pH scale ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic.
What is the pH of 10 10 HCl?
pH of Solution with Very Dilute Acid 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.
Is HCl a salt?
Hydrochloride (hydrochloride salt): A salt consisting of a chloride anion with the conjugate acid cation of a base, usually an amine. The generic structure is B-H+ Cl-. Pyridinium hydrochloride, a hydrochloride salt containing a pyridinium cation, can be formed by the reaction of pyridine with hydrogen chloride gas.
What is the pH of 1 M HCl?
Hi, as professor Thomas Proft said pH= -log[H3O+], thus HCl 1M has a pH=-1, however pH has been defined between 0 and 14, according to the water constant (pK=14).
Is HCl an acid or base?
On the other hand, substances such as hydrochloric acid, HCl, are held together by polar ionic bonds and when placed into water the hydrogen will break away to form hydrogen ions, making the liquid acidic. HCl therefore has a very low pH and is a very strong acid. Weak acids, with pH 5 or 6 are slightly more complex.
What is the pH of 10% HCl?

What is pH of 10 8m HCl?
The pH of 10^-8M HCl solution is: (1) 8 (2) 1 (3) Close to 7 (4) 0. HCl is a strong acid. All acids have a pH in the acid range, that is to say below 7.
