Answer: pH of HCl =5, HNO3 = 1, 
NaOH = 9, KOH = 12
Explanation:
pH = -log [H+ ]
1. 1.0 x 10^-5 M HCl
 pH = - log (1.0 x 10^-5)
 = 5 - log 1 = 5
2. 0.1 M HNO3
 pH = - log (1.0 x 10 ^ -1)
 pH = 1 - log 1 = 1
3. 1.0 x 10^-5 NaOH
 pOH = - log (1.0 x 10^-5)
 pOH = 5 - log 1 = 5
 pH + pOH = 14
 Therefore , pH = 14 - 5 = 9
4. 0.01 M KOH
 pOH = - log ( 1.0 x 10^ -2)
 = 2 - log 1 = 2
pH + pOH = 14
Therefore, pH = 14 - 2 = 12
 
 
        
             
        
        
        
This is thermodynamics. When you increase the temperature of an object, the particles gain on kinethic energy ergo the move faster. When you decrease it, they slow down.
