1.What is ph scale?

Question

Give me short and cleare definition

Answer 1

a ph scale is a measure of acidity or basicity on a level 14. below 7 is acidic and above 7 is basic.7 is neither acidic nor basic

Answer 2

PH scale, is a scale showed the concentratrion of hydrogen ions in a slolution, starting from 0-14, the lower ph value is the high acidic solution(i,e 0- nearly 7 is acidicsolutions) , when ph=7 the soluiton is nurtal( niether basic nor acidic) , ph more than 7 the solutions are basic,the eqution for ph, is
ph= - log [H+]

Answer 3

It's the logarithm of the concentration of positive hydrogen ions in a mixture or substance. The lower the Ph, the high the concentration, and the more acidic the substance. The higher the Ph, the lower the concentration, and the more basic the substance.

Ph ranges from 1 (highly acidic) to 7 (neutral), to 14 (highly basic).

Hope that helps!

Answer 4

The concentration of hydrogen ions in a solution is very important for living things. This is because, since the hydrogen ions are positively charged they alter the charge environment of other molecules in solution. By putting different forces on the molecules, the molecules change shape from their normal shape. This is particularly important for proteins in solution because the shape of a protein is related to its function.

The concentration of hydrogen ions is commonly expressed in terms of the pH scale. Low pH corresponds to high hydrogen ion concentration and vice versa. A substance that when added to water increases the concentration of hydrogen ions(lowers the pH) is called an acid. A substance that reduces the concentration of hydrogen ions(raises the pH) is called a base. Finally some substances enable solutions to resist pH changes when an acid or base is added. Such substances are called buffers. Buffers are very important in helping organisms maintain a relatively constant pH.

Answer 5

Ph scale is the scale determining the concentration of given solution.
mathematically
Ph= - log [H+]
where [H+] is concentration of hydrogen ion in the given solution
fact is that
Ph 1-6: acidic solution eg : HCl
Ph 8-14: basic solution eg : ammonia
Ph 7: neutral solution eg : Water

Answer 6

A scale from 0 to 14 reflecting the concentration of hydrogen ions in solution; the lower numbers denote acidic conditions and the upper numbers denote basic, or alkaline, conditions.

Answer 7

0 to 14, 0 - 6 Acidic, 7 neutral, 8 - 14 Basic

Answer 8

ph is a scale, 0 to 14 where from 7 is neautral, (water) and below 7 is acidic, and above is basic. acidic is course, hair is acidic, milk is acidic. basic is soft, laundrey detergent is acidic, and the burn when you eat a jalapenio is a basic burn.

Answer 9

pH is the power of hydrogen which detects the acidity and basicity of a solution

Answer 10

less than 7 is acidic
7 is neutral
7-14 is a base
