To find pH, use the following formula ---> pH= - log [H+]
so first we need to calculate the [H+] concentration using the OH concentration. to do this, we need to use this formula--> 1.0x10-14= [H+] X [OH-], so we solve for H+ and plug in
[H+]= 1.0X10-14/[OH-]---> 1.0 x 10-14/ 1.0 x 10-4= 1.0 x 10-10
now that we have the H+ concentration, we can solve of pH
pH= -log (1.0x10-10)= 10

Answer: Hello the compound is missing but I was able to get the Full question and missing compound . ( compound = copper sulfate )
<em>answer</em> : statement ; 2 , 3 and 5
Explanation:
The true statements regarding the coordination compound ( copper sulfate ) are : 
- The ligand must have at least one unshared pair of valence electrons in order to covalently bond with transition metal in the coordination compound  ( statement 2 )
 - Ethanol was used during crystallization of the coordination compound because the compound is soluble in ethanol ( statement 3 )
 -  The colors of many coordination compounds are the result of light absorption by the d electrons on the transition metal ( statement 5 )
 
During the coordination of compounds dative bonds exits between the transition metals and the Ligands molecules 
 
        
             
        
        
        
First write all of the compounds/atoms in either side then fill in existing values and balance
