Calculate the concentration of an aqueous solution of naoh that has a ph of 11.98.

0.001 mol/L. The concentration of an aqueous solution of NaOH with a pH

of 11 is 0.001 mol/L

Step 1. Calculate the pOH of the solution

pOH = 14.00 – pH = 14.00 -11 = 3

Step 2. Calculate the concentration of NaOH

[NaOH] = [OH^(-)] = 10^(-pOH) mol/L = 10^(-3) mol/L = 0.001 mol/L

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
