Volume of HCl used 25.0mL 4 l
borishaifa [10]

Answer:

1.0 M

Explanation:

Reaction equation;

KOH(aq) + HCl(aq) -----> KCl(aq) + H2O(l)

Concentration of acid CA = ?

Concentration of base CB = 1.0 M

Volume of base VB = 25.60 - 0.50 = 25.1 ml

Volume of acid VB =  25.0 ml

Number of moles of acid NA = 1

Number of moles of base NB =2

CAVA/CBVB =NA/NB

CAVANB = CBVBNA

CA = CBVBNA/VANB

CA = 1 * 25.1 * 1/25.0 *1

CA = 1.0 M

write a balanced equation to determine the molarity of the HCI solution when a 24.6 ml sample of HCI reacts with a 33.0 mL of 0.
MatroZZZ [7]

Answer: 0.30 M

Explanation:

HCl+NaOH\rightarrow NaCl+H_2O

According to the neutralization law,

n_1M_1V_1=n_2M_2V_2

where,

M_1 = molarity of HCl solution = ?

V_1 = volume of HCl solution = 24.6 ml

M_2 = molarity of NaOH solution = 0.222 M

V_2 = volume of NaOH solution = 33.0 ml

n_1 = valency of HCl = 21

n_2 = valency of NaOH = 1

1\times M_1\times 24.6=1\times 0.222\times 33.0

M_1=0.30M

Therefore, the molarity of the HCI solution is 0.30 M
