What is the pH of Windex?
84416
Yeah, whoever said that Windex was acidic is a little confused.  \nWindex's main ingredient is ammonia, which is NH3.  When ammonia is dissolved in solution like in Windex, it forms ammonium hydroxide, NH4OH.  Windex has that ammonia smell to it, right?  This ammonia ingredient puts Windex's basic pH at around 12; ammonia is a weak base.  You can always find out for yourself by getting some pH or Hydrion paper and testing Windex.

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

pH = -lg [H+]\n\nHence, \npH = 3 means [H+] = 10^ -3\npH = 5 means [H+] = 10^ -5\n\npH = 3 has 100 times more H+ ions in the same volume of solution than that of a pH = 5, which means it is 100 times more acidic

pH= -log(6.0 x10^-3)\npH is about 2.22

Water... its got a pH=7

Hummm:  You can calculate the [OH-] from the pH.  [OH-] = 10^-2.  pH + pOH = 14 (from [H+]x[OH-] = 10^(-14):  pOH = 14 - 12 = 2.  Find the solubility product for iron (III) hydroxide in a table in the back of your textbook or a handbook of Chemistry or physics. Kp = [Fe+3] x [OH-]^3. Substitute numbers in and solve for [Fe+3].  This is also the molar solubility as one mole of iron hydroxide contains one mole of Fe+3.

Mg(OH)2  --->  Mg^2+  +  2OH^-\n\nk(sp) = [Mg^2+][OH^-]^2 \n\nIf pH = 12.8, then\npOH = 14 -12.8 = 1.2\ntherefore, [OH^-] = 10^1.2 =  0.0631 (ask your calculator!)\nnow, k(sp) = 1.2 * 10^-11 = [Mg^2+] [0.0631]^2 \nIf you solve for [Mg^2+] , you will have the answer.\n\nIf you need more help, please email me or re post.

the moles of NaOH = the moles of OH - = 0.125 * 0.606 = 0.07575\nthe moles of OH - in the new solution = 0.07575/(15 + 0.125 ) = 5*10^(-3) M\npOH = - log ( 5*10^ -3) = 2.3\n=> pH = 14 - pOH = 11.7

If the pH is 4, the pOH is 10 (pH + pOH = 14).  10^(-pOH) = [OH-].\n\nAnswer is 1E-10

pH = pKa - log (.25/.4) ~= 4.3

The pH scale goes from 1-14, with 1 being the most acidic, 14 being the most basic, and 7 being neutral. \n\nSince a pH of 9 is closer to neutral than extremely basic (pH = 14), I would call the window cleaner weakly basic.

The pH level. 7 is neutral. Below 7 is acidic and above 7 is basic. 1 being most acidic and 14 being most basic.

we know that pH is ranged from totally basic to totally acidic, with neutrality (water) being at pH=7; so just display a range from 0 to 14 and color code it (red for acid and blue for basic) and place your findings there (ie before and after situations of NaCl towards the pH of the solution). Also place analogies (ie. the results of the pH due to NaCl concentration of 10% is equivalent to household ammonia)\n\nWhen explaining something to a non-science person, visuals and analogies always helps.
