mossoi Posted February 10, 2004 Share Posted February 10, 2004 My Dremmel is very good at etching glass. How do I find out if it's an acid or a base? Link to comment Share on other sites More sharing options...
Sayonara Posted February 10, 2004 Share Posted February 10, 2004 Wrap it in litmus paper and throw it in the bath. Link to comment Share on other sites More sharing options...
YT2095 Posted February 10, 2004 Share Posted February 10, 2004 and no putting in Radox or Bath Salts, it`ll falsify your results as they`re both Base Link to comment Share on other sites More sharing options...
ed84c Posted February 10, 2004 Author Share Posted February 10, 2004 In theory though using an electric pH measurer (yes ignore potential differences) would it register as pH 0? Link to comment Share on other sites More sharing options...
Sayonara Posted February 10, 2004 Share Posted February 10, 2004 You mean your beaker full of protons from the first post? Link to comment Share on other sites More sharing options...
YT2095 Posted February 10, 2004 Share Posted February 10, 2004 would what register as zero dude? Link to comment Share on other sites More sharing options...
mossoi Posted February 10, 2004 Share Posted February 10, 2004 My Dremmel is registering as 0. I think it might be broken - although it is still etching. Link to comment Share on other sites More sharing options...
JaKiri Posted February 10, 2004 Share Posted February 10, 2004 YT2095 said in post # :would what register as zero dude? When the concentration of H+ (or, more correctly H3O+) is equal to the concentration of the acid. Basically (boom boom). (How do you do superscript?

wolfson Posted February 11, 2004 Share Posted February 11, 2004 You can have a minus pH, and a pH of above 12. Link to comment Share on other sites More sharing options...
ed84c Posted February 11, 2004 Author Share Posted February 11, 2004 The pH of the beaker of protons would register as zero. Link to comment Share on other sites More sharing options...
greg1917 Posted February 11, 2004 Share Posted February 11, 2004 Kids are told in school that there is a pH range of 1-14 purely for the reason that they wont encounter anything outside this range in school, and its reasonably simple for their minds to grasp. By the time you actually move onto to pH calculations, conjugate bases and all that monkey business, it will become evident the pH range can go below 0 and above 14. pH doesnt stand for anything, its a mathematical operation involving the concentration of hydronium ions. pH = -log[H30] Thus for a very high hydronium ion concentration, say for example 20M, the pH will be -1.3.

wolfson Posted February 11, 2004 Share Posted February 11, 2004 When you have more protons the ionisation of the indicator moves in the reverse direction so that less is ionised, the more protons the more acidic I think if you had a beaker full the the pH would be very much so minus.

wolfson Posted February 11, 2004 Share Posted February 11, 2004 Oh lol and also on that link i put in on the previous page, I have explained how to clalculate pH, for acids and bases (using Kw). Link to comment Share on other sites More sharing options...

(baths and stuff?). PH would still be at 7, but you`re quite right, it wouldn`t register that`s why the passive PH meters use center calibrated needles and the 2 disimilar matals (Alu and Iron usualy). in water there will be no reaction and the needle will not move, but on the meter the markings will say PH 7 at center position the interesting part happenes when the probes are in an acid , one will be + the other - and so the needle will swing one way. in an alkaline it will be the opposite and so the needle will go the other way most DVM`s work the same way (Digital Volt Meters), only difference is that no voltage (ph 7) will read as 0.00 depending on what metal you have on what electrode it will read a voltage 1.45 v for example, now use the same electodes in an alkaline it may read -1.12. now, change on the LCD screen the "-" sign to ACID or Alkaline and you have your PH meter, of course, the 0.00 in water will have to be changed to 7.00, but it`s digital, that`s literaly seconds of work to a manufacturer hope that helps a little Link to comment Share on other sites More sharing options...

JUST OH ions only, nope, it`s not possible to my knowledge secondly: they try sell anything on Ebay, I really wouldn`t be surprised if someone claims to have a bag of dried protons on there ))) Link to comment Share on other sites More sharing options...
