How do you measure pH without a pH meter?
We can use a pH paper.
What do you measure pH?
The pH of solutions (liquids) is measured.
How does the pH of a concenterated acid change when it is diluted?
pH is actually a measure of hydrogen ion concentration, similar to how molarity is a measure of the concentration of other solutions. The pH of the acid will become more neutral, in this case higher if it's being diluted with water.
Why was it necessary to dilute substances f and m before measuring the pH?
Diluting substances F and M helps to ensure that the pH measurements are accurate and reliable. Dilution can prevent the substances from being too concentrated, which may affect the electrode response and result in erroneous pH readings. Dilution also helps to minimize potential interferences that may be present in the original sample.
What is a true pH?
pH is a measure of acidity or alkalinity of a solution.
Is it true that a ten-fold dilution of a strong acidic solution will decrease the pH by 1?
No, it is false. A ten-fold dilution of an acid will INCREASE the pH by 1 unit. Remember pH is 0-14 where 0 is most acidic. Diluting ten-fold on a logarithmic scale will increase the pH.Conversely, a ten-fold dilution of an alkali/base will increase the pH by 1 unit.
If you took a solution of pH 5 and diluted it with water the pH number would be?
Diluting with water will make this solution more neutral, meaning it will slowly increase to 7, which is the pH value of pure water used for this dilution.
Will pH of the acid change after the dilution?
can you be more specific? "the" acid? pH of buffered solutions generally will not change upon dilution, following the henderson-hasselbach. however, pH of strong acids will change, following the standard equation: pH = -log[H+] yerp
How does buffer dilution affect the effectiveness of a solution in maintaining a stable pH level?
Buffer dilution decreases the effectiveness of a solution in maintaining a stable pH level because it reduces the concentration of buffering agents, making it less able to resist changes in pH when acids or bases are added.
What is the effect of dilution on the pH of strong acid?
Diluting a strong acid will generally have little effect on its pH. This is because strong acids completely dissociate in water to give H+ ions, so adding more water will not change the concentration of H+ ions significantly. Therefore, the pH of a strong acid solution remains relatively constant upon dilution.
Why does the pH of an acetate buffer increases after dilution with water?
The increase in pH of an acetate buffer after dilution with water is due to the decrease in the concentration of the acetic acid and acetate ions in the solution. This decreases the buffering capacity of the solution, causing the pH to shift towards the pKa of acetic acid (4.76) as the system is no longer able to resist changes in pH as effectively.
What is the maximum pH attained upon infinite dilution of an acid?
Trick question ? If you dilute with water then eventually the pH will approach 7 (approximately, since water seldom has a true pH of 7).

Why does pH of a solution decrease upon dilution?
The definition of diluting something is to make it weaker. So when diluting the pH of a solution, you are making it weaker and therefore decreasing the pH level.Added:The real answer is somewhat more complicated: In fact it depends on what the original pH (acidity or alkalinity) was before dilution took place, the complicating factor is that dilution is (supposedly) done with water that by itself contains both H+ AND OH- ions (in neutral water both are very low, concentration of 1.0*10-7 mol/L, that's why the pH of water is 7.0!)Answer: On dilution with water pH always tends to 7, meaning increase of pH value when pH was originally below 7 (acidic, conc. [H+] more than 1.0*10-7 mol/L) AND decreasing pH when it was originally above 7 (alkaline, conc. [H+] less than 1.0*10-7 mol/L or conc. [OH-] more than 1.0*10-7 mol/L)
What can be used instead of phenolphthalein to measure pH?
Other pH indicators like bromothymol blue, methyl red, or universal indicator can be used as alternatives to phenolphthalein for measuring pH. Additionally, pH meters can provide a more accurate and continuous measurement of pH compared to indicators.
