If it requires 30.0 milliliters of 1.2 molar hcl to neutralize 20.0 milliliters of naoh, what is the concentration of the naoh solution? balanced equation: naoh hcl nacl h2o 0.60 m naoh 0.80 m naoh 1.3 m naoh 1.8 m naoh

Respuesta :

1.8 MNaOH
glad I could help

Answer: The correct answer is 1.8 M NaOH.

Explanation:

The balanced chemical reaction for the neutralization of NaOH with HCl follows:

[tex]NaOH+HCl\rightarrow NaCl+H_2O[/tex]

To calculate the molarity of the NaOH for neutralization, we use the equation:

[tex]M_1V_1=M_2V_2[/tex]

where,

[tex]M_1\text{ and }V_1[/tex] are the molarity and volume of HCl.

[tex]M_2\text{ and }V_2[/tex] are the molarity and volume of NaOH.

We are given:

[tex]M_1=1.2M\\V_1=30mL\\M_2=?M\\V_2=20mL[/tex]

Putting values in above equation, we get:

[tex]1.2\times 30=M_2\times 20\\\\M_2=1.8M[/tex]

Hence, the correct answer is 1.8 M NaOH.
