Answer to Question #117644 in General Chemistry for Clara

Question

Type of solution

1. Given 10 mL NaOH solution (strong base) of pH=12 and 5 mL HCl solution
(strong acid) of pH=1
1.1. Determine the concentration of H + ions in the acid solution, then deduce
HCl concentration.
1.2. Determine the concentration of OH - ions in the base solution , then
deduce NaOH concentration.
2. The above solutions are mixed.
Is the mixture acidic, basic or neutral? Justify by calculation

I just need help with nbr 2 to know if I did it correct or not. thx.

Answer 1

1.1. 1M

1.2. 0.1M

2.[H+]=(5*1-10*0,1)/15 = 0.267

Acidic
