WebbA 10–25% solution of sodium hypochlorite is, according to Univar's safety sheet, supplied with synonyms or trade names bleach, Hypo, Everchlor, Chloros, Hispec, Bridos, Bleacol, or Vo-redox 9110. A 12% solution is widely used in waterworks for the chlorination of water, and a 15% solution is more commonly used for disinfection of waste water ... WebbThe given pH of HCl is 2; The given pH of NaOH is 12; We have to find the resultant pH. [HCl] = [NaOH] = So, the reaction goes like this : Since , before reaction; After reaction; 0 1 2 2 We will be finding the concentration of the hudroxide ion first. left from NaOH = M The Ph of the hydroxide ion is calculated as Since , we know that

Water Pyrrolidine: 19.56: 10.8: 11.4 WebbExample #1: Here's a variant that's not framed in a tricky way: Show that the pH of a solution remains 7.00 when 1.0 x 10¯ 11 moles of HCl is added to the solution. Solution: 1) pH of 7.00 means this: [H +] = 1.0 x 10¯ 7 M. 2) Add 1.0 x 10¯ 11 moles of H + to get: 1.0001 x 10¯ 7 M pH = −log 1.0001 x 10¯ 7 = 6.9999566 3) Round the answer off to two … philippine national museum location
