37. Option: C
The neutralization equations for hydrochloric acid with sodium hydroxide can be written in
three forms below:
HCl(aq) + NaOH(aq) → H2O(l) + NaCl(aq)
H+(aq) + Cl–(aq) + Na+(aq) + OH–(aq) → Na+(aq) + Cl–(aq) + H2O(l)
H+ + OH–→H2O (l)
38. Option: C
Concentration of hydroxyl ions given a PH of 5:
Given the equation below
PH + POH = 14
Log [OH-] = -POH
10log [OH-] = 10 -POH
This will get to:
POH = 14 – 5 = 9
[OH-] = 10-POH
=1 * 10-9
39. Option: C
