What if you lived on a planet identical to earth but for which room temperature was 50C. How would the pH scale be different?
Step 1 of 3
Example 14: 25 mL ClNH3 0.1 HCl initial pH pKb= 4.75 NH3+HCl>NH4Cl NH3+H2O>NH4++OH kb=[NH4+][OH]/[NH3] kb=10^4.75 x +x +x 1.8x10^5=x^2/0.1 142.87=11.13 0.1 +x +x x=[OH]=1.34x10^3 M log(1.34x10^3)= 2.87 pH after adding 5mL HCl 0.250(0.10)2.5x10^3 pH=pka+logNH3/NH4+ 5.0x10^4 5x10^4 5x10^4 pH=9.25+log(0.0667/0.017)=.84 2.0x10^3 0.014 at equivalence NH3+HCl>NH4HCl 2.5x10^3 0.050 mol HCl/ T volume 2.5x10^3 0 2.5x10^3 5.6x10^10=x^2/0.050 x=2.3x10^6 0 2.5x10^3 0 NH3 NH4+ H3O+ pH= log(0.2.4 )= 0 0.050 0 +x 0.050x +x Add 30 mL HCl HCl= 0.0091 Molar so
