Finish the reaction equation
HCl + NaOH --> ____ + ____
H2O and NaCl
In a titration, 16.0 mL of 0.18 M NaOH exactly neutralizes 24.0 mL of HCl. Determine the molarity of the HCl solution.
0.12 M
HCl +H2O --> H3O+ + OH-
What does the water molecule act as and why?
It acts as a base because it accepts H+ ions
In a lab, a student titrates a 20 mL sample of HCl using 0.025 M NaOH. In one of the titration trials, 17.6 mL of the base solution neutralizes the acid.
Show a numerical setup for calculating the concentration of hydrochloric acid using the titration data. (Must show units)
MaVa = MvVb
Ma(0.02 L) = (0.025 M)(0.175 L)
Ma = (0.025 M)(0.175 L)/(0.02 L)
Ca(OH)2 + H2SO4 --> ____+ 2H2O
Complete the above neutralization reaction.
CaSO4
