If a substance has a pH of 1 is it a strong or weak acid?
Strong because a substance with a pH of 7 is considered neutral, so the further away from 7 the pH gets, the more strong of an acid it becomes.
What is the difference between a pH of 6 and a pH of 8 in H plus concentration terms?
The difference between a pH of 7 and a pH of 8 are as follows:A pH of 7 means the concentration of [H+] is 10-7.A pH of 8 means the concentration of [H+] is 10-8.Therefore, a substance with a pH of 8 has 1/10th the concentration of hydrogen ions that a substance with a pH of 7.
The term pH is used in measuring?
pH is measured on a logarithmic scale of 1 to 14. 1 is the most acidic, and 14 is the most alkalinic. An acidic substance has a high amount of H+ ions and an alkalinic substance has a high amount of OH- ions.
What does a chemicals PH tell us about the chemical?
It tells about the degree of acidity or alkalinity of a substance. The pH is a measure of the concentration of hydrogen ions present. pH = - log10 [H+] Example: concentration of H+, [H+] = 0.010 M pH = - log10 0.010 = 2 pH = 5 [H+] = 10-5 M = 1 x 10 -5 M pH = 3.5 [H+] = 10-3.5 M = 3.2 x 10-4 M
When the pH is high the concentrations of hydrogen ions is?
pH refers to hydrogen parts the lower the hydrogen parts the more acidic a substance is the higher adversely relates to how alkaline or basic a substance is it is scaled from 1-14 i being the most acidic 14 being the most basic when the pH is high, then the concentration of Hydrogen(H+) ions is low
What is the pH value of a substance known to be an acid?
The pH is measured from 1 to 14. From 1 to 6.0 the substance is acidic.
At what pH is a substance an acid or a base?
The pH is measure from 1 to 14. so, from 1 to 6.9 the substance is acidic. and from 7.01 to 14 the substance is basic. 7 is neutral. The closer the substance is to 7 it is either basic or acidic. As the number is lower the substance is more acidic for example: pH 2.9 is more acidic than pH 4.8
What are three safe methods to test for an acid?
1. Test with a pH paper. 2. Test with a liquid or solid pH indicator. 3. Measure the pH with a pH-meter.
If a substance is added to water and the pH decreases is that substance an acid or a base?
pH of 1 to < 7 indicates an acid pH of >7 to 14 indicates a base pH of 7 indicates water
What scale is pH?
PH scale is a scale that shows the substance is PH ....... Example: The substance is PH 7, so it is neutral The substance is PH 3, so it is acid The substance is PH 10, so it is alkali
What substance has a pH level of 1?
Hydrochloric Acid
A substance of PH 1 is?
acid
What is the name for a substance in the pH scale that is under 7?
It`s called acid(such as HCl,,,,PH=1)
What is alkalis acid?
Alkali isn't an acid. Alkali and acid are terms used when the pH of a substance is a certain number, for example if a substance has a pH of 1, 2, 3, 4, or 5, then the substance is an acid. If the pH is 11, 12, 13, 14 or 15, then the substance is an alkali.
If a substance has a pH of 1 is it a strong or weak acid?
Strong because a substance with a pH of 7 is considered neutral, so the further away from 7 the pH gets, the more strong of an acid it becomes.
What type of substance have a pH between 1 and 6?
Acids.
What does pH1 mean?
A pH of 1 means that a substance is extremely acidic.
