Find the percent ionization of a 0.175 M CH3CH2CO2H solution. The Ka for CH3CH2CO2His 1.3 x 10^-5. I am getting [H+] =Sqr (.175)(1.3*10^-5)

Then taking [H+]/ [acid] initial

What am I doing wrong here?

Tolerance to high levels of salinity

Ok where is the image ?

The answer is the first option just took the test

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na
