It is important to know the PH of various substance so as to prevent damage to the human beings and certain materials. The knowledge of PH is also important in environmental and water analysis.

Why was it necessary to dilute substance before measuring the pH?
This is necessary only for very concentrated acids or bases.
Do you use a decreaser to lower your pH levels?
Yes, you can add an acid: the minimum quantity necessary.
What indicator is used in the preparation of sodium chloride?
An indicator is not necessary; but if you want phenolphthalein is colorless at pH=7.
What conditions are necessary for the enzymatic breakdown of protein into peptides?
Low pH(HCl) amylase incubated at 100c
Is 2.77 a normal pH for hydrochloric acid thats 1M If not then how should I calibrate my pH meter at home?
No, pH 2.77 is not the correct pH for 1 M HCl. The pH of 1 M HCl should be 0 (zero) because pH is the negative log the the H+ and for 1 M HCl the [H+] is 1 M, and the negative log of 1 is 0.
Who measures pH?
I do, because I have a Hot Tub, and maintaining a proper Ph is necessary for proper maintenance.

Why is it necessary to standardize a pH meter?
A pH meter must be standardized because it measures relative potentials and thus relative pH. It is necessary to know to what the measurement is relative. A standard must be measured and the meter set to the known value for this standard. The pH values of other solutions are then measured relative to this standard.
How do you correct the pH of water?
By adding the necessary reagent, acidic or basic.
What level pH is necessary to grow collards and turnips.?
Between 6.5 and 7.5.
What does sodium bicarbonate do in lotions?
Adjusts pH upward. Sodium hydroxide can also be used if necessary--for large pH shifts or very large batches.
What pH is necessary to kill botulism?
When canning, the pH does not kill botulism. Rather, a pH less than 4.6 is needed to prevent botulism from growing. If you are canning foods with a pH at or over 4.6, a pressure canner is needed to completely kill botulism.
How can a person distinguish among acids bases and neutral substances?
With a pH meter or pH paper. Other indicator dyes (e.g. litmus, phenolphthalein) may be used if it is not necessary to determine the exact numerical pH value.
Do you use a decreaser to lower your pH levels?
Yes, you can add an acid: the minimum quantity necessary.
What information is necessary to determine the pH of a solution when you given hydroxide ion concentration?
You will need Kw to determine the concentration of hydrogen ions and You will need the formula pH = -log[H+]
What conditions are necessary for the enzymatic breakdown of protein into peptides?
Low pH(HCl) amylase incubated at 100c
What indicator is used in the preparation of sodium chloride?
An indicator is not necessary; but if you want phenolphthalein is colorless at pH=7.
