CHM1045 : pH Acids - Bases
Document Summary
Showing all work, calculate the ph from the following hydrogen ion concentrations or hydroxide ion concentrations and state whether each solution is an acid, a base, or neutral. [h+] = 1. 0 x 10-3 m ph _- - log [1. 0 10-3]=3. 0 acidic. [h+] = 2. 4 x 10-5 m ph= - log [2. 4 10-5]=4. 6 acidic. [h+] = 5. 11 x 10-13 m ph= - log [5. 11 10-13]=12. 3 base ph < 7 acid ph > 7 base ph =d neutral. [1-1-1]=1. 361 10-13 ph= - log [1-1-1] ph= -log [1-361 10-13] [h+] = 1. 0 x 10-7 m ph -- - log [1-0 10-7]=7 neutral. [oh-] = 6. 85 x 10-10 m port - log [6. 85 10-10]=9. 16. [oh-] = 4. 99 x 10-8 m: 0 10-14. Showing all work, calculate the hydrogen ion concentrations from the following phs and state ph = - log [3-389 10-1] = 0. 47 acid whether each solution is an acid, a base, or neutral. Acid: 3 = - log [1-1-1]
