<h3>What is the pH?</h3>The pH of a solution is what tells us if the solution is acidic or basic. The solution is acidic if the pH of the solution is less than 7.
1) pH = - log(3.5 x 10^-5 M)
= 4.45
Thus the solution is acidic.
2) We can see that the concentration as given is the concentration of OH^-
[OH ] = 4.0 x 10^-3 M
pOH = -log (4.0 x 10^-3 M)
pOH = 2.39
pH = 14 - 2.39
pH = 11.61
The equation of the reaction is;
Number of moles of NaOH = 0.40 M * 10/1000 = 0.004 moles
Number of moles of HCl = 0.20 M * 10/1000 = 0.002 moles
We can see that HCl is the limiting reactant
Mass of NaCl produced ;
0.002 moles * 58.5 g/mol = 0.117 g
