Salt hydrates are an important class of PCMs. An inorganic salt hydrate (hydrated salt or hydrate) is an ionic compound in which the ions attract a number of water molecules, which are then trapped inside the crystal lattice. A hydrated salt has the generic formula MxNy. nH2O.
Answer:
B
Explanation:
I am not sure but I think it is B. Out of all the answers that one makes sense.
Answer:
Row 1
pOh=14-pH=14-5.7=8.3
Hence, acidic
Row 2
pH=14-pOH=14 - 9.4 = 4.6
Hence, acidic
Row 3
pH = 8.15
pOH=14-pH=14 - 8.15 = 5.8
Hence, basic
Row 4
pOH = 5.70
pH=14-pOH=14 - 5.70 = 8.3
Hence, basic
