PH values of acids?
Acids generally have a pH ranging from 1 - 6. pH 1 being the most acidic, and pH 6 being the least acidic. eg, hydrochloric acid, nitric aicd, sulfuric acid has a pH of 1. Ethanoic acid has a pH of 3.
What value is used to express the acidity or alkalinity of a system?
Normally term,'PH' of a solution is used determine the strength of an acid which is nothing but the concentration of H+ ion concentration in a solution. ph= -log[H+] concentration.... since its -ve log hence smaller value of PH means it's more strong acid. ph=7 is value of water which is neutral. pH ranging below 7 are acids & above 7 are bases.
How does PCO2 level in blood affect the pH level in blood?
In healthy subjects the mean PCO2 fall 18 mm Hg from the baseline and mean PO2 rise 7 mmHg
What are facts about pH?
I think its cool that the pH scale is logarithmic! That means that a pH of 8 is 10 times more basic than a pH of 7! cool!Its also really cool that pH is the negative logarithm of the hydrogen ion concentration!theres a such things pH indicators which lets you know if the solution contains acidic base or notpH is a scale that measures acidity and basicity of a substance, with a usual range of between 0-14. The closer the value is to zero, the more acidic the substance is. The closer it is to 14, the more basic it is. However, some extreme substances can have pH of higher than 15 or lower than 0. pH is calculated by the equations:pH = - log [concentration of H+ ions](or)pH = 14 + log [concentration of OH- ions]Since it is a logarithmic scale, each number differs by a factor of ten from the next. For example, a substance of pH 3 is 10 times more acidic than a substance of pH 4.The pH scale was first used by a Swedish botanist, I believe, in his studies to determine the effects of acidity on plant growth. The scientific community liked the idea so much that it became official.
What is the pH scale?
The pH scale represents the relative concentration of hydrogen ions in a solution. 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. The pH scale is a scientific classification of how acidic or basic a substance is. The scale ranges form 0 to 14 -- a pH reading of 7 is neutral in nature , a pH less than 7 is acidic in nature and a pH greater than 7 is basic in nature.
Is a natural solution have a pH of 0?
I think you mean neutral. Google it.
What is a neutral pH mean?
The pH scale ranges from 0 to 14 such that something with a pH of 0 is extremely acidic and something with a pH of 14 is extremely basic. A neutral pH is in the middle and has a pH of 7. An example of something with a pH of 7 is rain water.
What is a pH element?
I'm not sure what you mean by a "pH element." pH is a measure of how acidic or basic a substance is on a scale from 0 to 14. It indicates the concentration of hydrogen ions in a solution.
What do mean pH scale?
The pH scale is from 0 to 14; pH is a measure of acidity/alkalinity of a solution.pH= 7 is neutral; under 7 is acidic, over 7 is alkaline.
An acid has a pH level of?
it has a pH level of 0-6.
Is pH scale range is less than 0?
The pH scale is between 0 and 14 but a pH under 0 is possible for some strong acids.
What does it mean when a substance has a low pH?
When a substance has a low pH, it means that it is acidic. pH is a measure of how acidic or basic a substance is on a scale of 0 to 14, with lower numbers indicating higher acidity.
What does 0-6 represnt on the pH scale?
It is the strong (pH=0) to weakly (pH=6) acid part of the pH scale.7 is neutral.
Can the pH level be 0?
No, the pH level cannot be 0. The pH scale ranges from 0 to 14, with 0 being the most acidic and 14 being the most basic. A pH of 0 is not physically possible as it would indicate a solution that is extremely acidic.
Why pH fall in between 0-14?
PH can be less than 0 and it can be more than 14. PH is -log of (H ) concentration. According to this the PH Of 1 M strong acid such as Hcl would be 0. similarly ... 10 M = pH -1 0.1 M = pH 1 0.01M = PH 2 0.001M = PH 3 0.0001M = PH 4 The pH scale is between 0-14 because the solution with which we generally encounter is in 0-14 range.
What does pH of 14 mean?
A pH of 14 indicates a strongly basic solution with a high concentration of hydroxide ions. It is at the extreme end of the pH scale, which ranges from 0 to 14, with 0 being highly acidic and 14 being highly basic.
What range is acidic?
pH = 0 to pH = 6 is the acidic range. pH - 0 is the most acidic.
