How many times a solution of pH 1 will be stronger than that of a solution having pH 2?
how many times a solution of ph 1 will be stronger than that of a solution having ph 2
What has the pH of 5.5?
Many substances have a pH of 5.5. For example, everyday rainwater has a pH from 5 to 6.5 usually.
What can be used instead of phenolphthalein to measure pH?
Litmus paper, or other pH papers can measure pH. Many pH test papers can measure specific pH values. There are also instruments called pH meters that can measure pH.
A pH of 5 is how many times as acidic as a pH of 6?
Ten times more acidic at pH=5 than at 6
How many times a solution of pH equals 3 be diluted to get a solution of pH equals 6?
The solution must be diluted 1000 times to get from a pH of 3 to a pH of 6.
How many significant figures are in the quantity 12.0 mL?
It is equally wrong to record too many digits, since this implies greater ... Thus, significant figures are those digits that give meaningful but not ... 3.43+8.6=12.0 ... 8 x 10-4 we can calculate the pH from the definition of quantity.
What is the pOH of a solution with OH 9.0 x 10?
pOH = -log [OH-], so pH = -log 9.0x10^-7pOH = 6.05 = 6.1 (to 2 significant figures)
If the pH of a solution is 3.9 what would the poh be?
10.1
Why is the pH scale significant?
The pH scale shows the relative acidity (H+ ions) and basicity (OH- ions) of a sample. A pH of <7.0 is acidic; a 7.0 pH is neutral and, one with a pH >7.0 is basic.
Is there a significant difference in the blood pH of different human races?
The Ph. of all human blood is the same. Different races of people do not possess different Ph. balances of their blood.
The body generates significant quantities of acids that may promote a disruptive?
decrease in pH :)
What organ controls pH levels?
Kidneys have the most significant role in regulating the blood PH level by controlling the excretion and reabsorbtion of the main acids and bases.
What happens to the buffer solution pH 7 when acid is added?
When acid is added to a buffer solution at pH 7, the pH of the buffer solution will decrease. However, due to the presence of a conjugate base in the buffer solution, the buffer will resist the change in pH and try to maintain its original pH value. This is because the conjugate base will react with the acid and prevent a significant decrease in pH.
How many times stronger is a pH of 5 than pH 8?
ph 5 is higher than ph 1
How many times a solution of pH 1 will be stronger than that of a solution having pH 2?
how many times a solution of ph 1 will be stronger than that of a solution having ph 2
Calculate the pH of a solution prepared by diluting 3.0 mL of 2.5 M HCl to a final volume of 100 mL with H2O?
Because HCl is a strong acid, it dissociates completely to H + Cl. Therefore, 3.0 mL x 2.5 M HCl = 7.5 meq of H+ . In 100 mL of solution, this is 0.075 M H+. pH= - log [H] = - log (0.075) = - (-1.1) = 1.1 (two significant figures)
What has the pH of 5.5?
Many substances have a pH of 5.5. For example, everyday rainwater has a pH from 5 to 6.5 usually.
