When blue vitriol is heated, those water of crystallization escape out of the crystal and what's left is anhydrous copper sulphate or simply CuSO4, without any water of crystallization.
Answer:
The pH of the solution is 5.31.
Explanation:
Let " is the dissociation of weak acid - HCN.
The dissociation reaction of HCN is as follows.
Initial C 0 0
Equilibrium c(1- ) c c
Dissociation constant =
In this case weak acids is very small so, (1- ) is taken as 1.
From the given the concentration = 0.050 M
Substitute the given value.
Therefore, The pH of the solution is 5.31.
If this is wrong im sorry, Im gonna go with 8.
Answer:
CL
because cleetus will rule the world
K = 39.09
Mn = 54.93
O = 15.99
KMnO4 = 39.09 + 54.93 + 15.99 x 4 => 157.98 g/mol
hope this helps!
