Um to my best knowledge I believe  it is the carbonated water 
        
                    
             
        
        
        
The answer would be the last one- it separates dissolved substances.
Have a great rest of your day!

Answer:
0.025536g
Explanation:
no. of mole = mass/Mr
mass = Mr ×  no. of mole
          = [23 + 1 + 12 + 3(16)] × 3.04×10^-4
          = 0.025536g
          = 0.0255g (3 significant figures)
 
        
             
        
        
        
PH scale is used to determine how acidic or basic a solution is.
we have been given the hydrogen ion concentration. Using this we can calculate pH,
pH = - log[H⁺]
pH = - log (1 x 10⁻¹ M)
pH = 1
using pH can calculate pOH
pH + pOH = 14
pOH = 14 - 1
pOH = 13
using pOH we can calculate the hydroxide ion concentration 
pOH = - log [OH⁻] 
[OH⁻] = antilog(-pOH)
[OH⁻] = 10⁻¹³ M
hydroxide ion concentration is 10⁻¹³ M
