If it requires 35.0 milliliters of 0.50 molar naoh to neutralize 25.0 milliliters of hcl, what is the concentration of the hcl solution? (3 points)
balanced equation: naoh + hcl yields nacl + h2o
select one:
a. 0.36 m hcl
b. 0.70 m hcl
c. 1.1 m hcl
d. 1.4 m hcl

b. 0.70 M HCl is the Answer

Explanation:

Molarity (M),  Molality (m), Normality (N),  Mass %,  Parts per million(ppm), billion(ppb), thousands(ppt)  are some of the terms we use to represent the concentration of the solution that is to represent the amount of solute present in a solvent.

The Balanced Chemical equation is :

Molarity is moles of solute present in 1L of the solution. The formula to find Molarity is

and its unit is mol/L

Rearranging the formula

We get                          

Moles = Molarity × Volume

Plugging in the values  

Mole ratio of NaOH: HCl is 1:1  

So moles of NaOH = moles of HCl  = 0.0175moles

So,
