how do you find ph of hot sauce in a chem class using ph paper?

You have to prevent the hotsauce from staining the pH paper. Run hotsauce through the filter paper; the pH of the filtrate will be about the same as the whole hotsauce.

Well to determine [H+] you use the equation that \npH=-log [H+] \nthus a solution with pH=3 will have a [H+] of 1x10^-3, \nand a solution with pH=8 will have a [H+] of 1x10^-8\nTo find [OH-] there are several equations you can use\n[OH-]=Kw/[H+], \nKw is the ionization constant of water which is equal to 1.0x10^-14\nThus you will have [OH-] of 1.0x10^-11 and 1.0x10^-6\nSo you answer will be that the solution with pH=3 will have a [H+]>[OH-]

seems like a homework question so use the equation pH=pKa + log [base]/[acid].  As a check for your answer when [base]=[acid]  the pH will equal the pKa.  the acid and base are  close in concentration so your answer will be around a pH=9.  pOH = 14-pH will help you on the other question.

pH = 4.75\n\ntechnically, the pH can be anything.  But, for the most effective acetic acid buffer, the pH would be 4.75 because the pKa of acetic acid is 4.75.  When the pH = pKa, the amount of acid and base are equal, thus its resistant to pH changes is greatest.

You get the little strips and dip them in a cup of whatever substance you are testing. Then the strip should change color based on its Ph level, and compare the strips to the little chart that comes with it to get the exact Ph level.\n\nPS. If you're testing a substance that isn't a liquid but is more gelly or if it is powder that has been reduced, add a little water, but make sure there are no chemicals in the water that will change the results.

The liquid should be clear...litmus paper is white usually...turns pink to red when in an unbalanced PH soulution....Yukoneze

The best method is pH meter (other than color indicator). \nTo measur the exact end point, what you have to is:\n\nStart the titration\nInsert a pH probe inside the solution\nNow start adding base to the acid and swirl the solution properly\nKeep track of your pH readings..\nYou will see a sudden jump (some thing like from 5.6 to 9.0 even with one drop addition)\nthats end point.

pH = -log ([H3O+])\npOH = -log ([OH-])\n\npH + pOH = pKw = 14\npOH = 14 - pH\n\n[OH-] = 10^-(pOH)\n\nPlug in and solve.

(.002mol /20ml) (1000ml / 1L ) = .10 M NaOH\n\n\n pOH =  -log 0.10 =  1\n\n pH = 14.00 - pOH   = 14 - 1  = 13 = D

use beers law to figure out the concentration and then take that to mole ratio

use the equation  pH= -lgKa+ lg( salt/acid)\n(this equation only applies for buffer system)

Go to any library of a chemical institute, school or university and try to find the "Handbook of Chemistry and Physics" which in the 1970ies was published yearly by CRC Press, 18901 Cranwood Parkway, Cleveland, Ohio 44128. The editor was Robert C. WEAST and this about 1000 or 2000 pages book among many many other physical properties also has a list of the heat of solution.

The American educational system is doomed.\n\nb) base is the best answer. The more basic, the higher the pH. More acidic=lower pH. Neutral=pH of 7 (pure water). Lemon juice would have a pH of 2 or so. Hydrochloric acid is near zero. Drain cleaner is like 13.\n\nAt least they still teach people how to use computers!
