Answer:
A. 2.45 L - Answer my answers is right.
Answer: pH of the solution is 12
Explanation:
NaOH —> Na+ + OH-
NaOH = 0.01M
Na+ = 0.01M
OH- = 0.01M
pOH = —log [OH-] = —log [0.01]
pOH = 2
pH + pOH = 14
pH = 14 — pOH = 14 — 2 = 12
pH = 12
_____NaOH + _____H2 SO4 _____ Na2SO4 + _____ H2O ,
To balance this equation,
Step 1:
Balance the number of sodium on both side:
by multiplying the NaOH by 2 that is:
2NaOH+H2SO4-------->Na2SO4+H2O
Step2:
As NOW the number of oxygen atom and hydrogen atom are not equal on both sides. So we multiply this H2O by 2 that is:
2NaOH+H2SO4-------->Na2SO4+2H2O
Now the no of all atoms on product side is equal to no of all atoms in the reactant side.
so the coefficient is 2 NaOH+1 H2SO4-------->1 Na2SO4+2 H2O.
