Question

Equal volumes of 0.1 M HCl and 0.1 M NaOH are mixed. The concentration of the mixture will be: (A) 2 M (B) 0.05 M (C) 0.02 M (D) 0.1 M

Tardigrade Admin · Accepted Answer

Concentration (M)=(M1 V1+M2 V2/ text total volume ) M1= molarity of HCl solution =0.1 M V1= volume of HCl solution =1 L m2= molarity of NaOH solution =0.1 M V2= volume of NaOH solution =1 L ∴ M=(0.1 × 1+0.1 × 1/1+1) =(0.2/2) =0.1 M

Q. Equal volumes of 0.1MHCl and 0.1MNaOH are mixed. The concentration of the mixture will be:

2 M

0.05 M

0.02 M

0.1 M

Concentration (M)= total volume M1​V1​+M2​V2​​ M1​= molarity of HCl solution =0.1M V1​= volume of HCl solution =1L m2​= molarity of NaOH solution =0.1M V2​= volume of NaOH solution =1L ∴M=1+10.1×1+0.1×1​ =20.2​=0.1M

Q. Equal volumes of $0.1 M H Cl$ and $0.1 M N a O H$ are mixed. The concentration of the mixture will be:
