A) acids because they start with h
The answer is salinity, salinity is the saltiness or dissolved inorganic salt content of a body of water.
HCl is an acid
C5H5N is a base
Cl- is a base
HC5H5N+ is an acid
Ca(OH)₂: strong base
pOH = a . M
a = valence ( amount of OH⁻)
M = concentration
Ca(OH)₂ ⇒ Ca²⁺ + 2OH⁻ (2 valence)
so:
pOH = 2 x 0.005
pOH = 0.01
pH = 14 - 0.01 = 13.99
