What numbers are higher and lower on the pH scale?
The pH scale is from 0 to 14. From 0 to 7 is acidic, and from 7 to 14 is basic. 7 is neutral. pH stands for "power of hydrogen".
What does it means if a solution has a pH of 3 12 2 7 or 9?
On the pH scale, lower numbers are more acidic, higher numbers are more basic (alkaline). 1 is the strongest acid, 14 is the strongest base, 7 is neutral.
5 why is Gypsum is a 2 on Mohs hardness scale while topaz is an 8 Can gypsum scratch topaz?
No, gypsum cannot scratch topaz. Minerals with a higher number on the Moh's Hardness Scale can scratch minerals that are lower-numbered, but lower numbers can't scratch higher numbers. A mineral would have to have a number higher than an 8 on the Moh's hardness scale in order to scratch topaz.
Higher the number on the pH scale the more acidic a solution?
The solution is basic.
What scale is used to determine whether a solution is an acid or base?
When referring to acidity of a solution one uses the pH scale. The lower the number, the higher the acidity. Pure water is said to be neutral, and is a 7 on the scale. Anything with a lower number ranking is acidic, and anything with a higher ranking is basic.
Is a pH of 11 acidic or basic?
Basic, because on the pH scale, 7 is neutral. lower than 7 is acidic and highr than 7 is Basic. Since 11 is higher than 7, it is basic.
What number on the pH scale are basic?
The numbers 7.1 through 14 are the basic numbers.
How are acids and bases related to neutralization?
By the pH scale which runs from 0 to 14. Seven, the midpoint, is neutral - like distilled water. Lower numbers on the scale are progressively more acidic, higher numbers are progressively more alkaline.
What chemical symbol represents an acid?
There is no particular symbol for acids. Different acids have different formulae. But sometimes to show that a reaction is taking place in acidic medium, the sign of H+ is used because all acids give H+ ion.
Does milk of magnesia have basic properties?
Yes-- Milk of Magnesia is a 10.5 on the pH scale, thus making it a base. (pH of 7 is neutral-- higher is more basic, lower is more acidic)
What is a pH scale and draw a pH scale?
The pH scale is often indicated as a vertical bar graph with scaled numbers from 0 to 14 (top to bottom). The lower numbers at the top are the more acidic pH, while the higher numbers near the bottom are more "basic" or alkaline. A color range indicates the relative pH using a rainbow, red-to-blue, or other color scheme.
Which pH value indicates the highest concentration of hydroxide ion?
The pH scale works like this:1 being acidic, like lemon juice,10 is basic, amoniathe lower the number the more acidic, higher numbers are basic and 7 is neutralthe stronger the base, the higher the number, which means a higher OH ion concentration. the stronger the acid, the lower the number, means a higher H3O ion concentration and a lower OH concentration.
