Calculate the sulfide ion concentration in a saturated H2S solution
when the ph is 0.5.
The concentration of H2S in a saturated H2S solution is about
0.1 mol/L.
H2S(aq) + 2H20 (l) -----> 2H30+ (aq) + S2- (aq)
Ka = 1.1 x 10 ^-21
Solutions
Expert Solution
pH = 0.5
[H2S] = 0.1 mol/L = 0.1M
Initial 0.1 0 0
Final (0.1 - x) (2x + 0.3010) x
assuming 0.1 - x = 0.1 and (2x + 0.3010 = 0.3010) [ since x is very small value]
Hence the sulfide ion concentration is equal to 1.214 * 10^(-21)
