Explanation:
H2SO4 + 2KOH → K2SO4 + 2H2O
From the question:
nA = 1
nB = 2
From the question given we obtained the following information:
Ma = 0.43M
Va =?
Mb = 0.35M
Vb = 120mL
Using MaVa / MbVb = nA/nB, we can easily find the volume of the acid required. This is illustrated below:
MaVa / MbVb = nA/nB
0.43 x Va / 0.35 x 120 = 1/2
Cross multiply to express in linear form
2 x 0.43 x Va = 0.35 x 120
Divide both side by the (2 x 0.43)
Va = (0.35 x 120) /(2 x 0.43)
Va = 48.84mL
Therefore, the volume of H2SO4 required is 48.84mL
Ответ:
The volume of the H2SO4 solution is 48.8 mL
Explanation:
Step 1: Data given
Molarity of H2SO4 solution = 0.43 M
Volume of KOH = 120 mL
Molarity KOH = 0.35 M
Step 2: The balanced equation
H2SO4(aq) + 2 KOH(aq) → K2SO4(aq) + 2 H2O(l)
Step 3: Calculate the volume of H2SO4
b*Ca*Va = a*Cb*Vb
⇒ b= the coefficient of KOH = 2
⇒ Ca = the molarity of H2SO4 = 0.43 M
⇒ Va = the volume of H2SO4 = ?
⇒ a = the coefficient of H2SO4 = 1
⇒ Cb = the molarity of KOH = 0.35 M
⇒ Vb = the volume of KOH = 0.120 L
2*0.43 *Va = 1*0.35 * 0.120 L
0.86 Va = 0.042
Va = 0.0488 L = 48.8 mL
The volume of the H2SO4 solution is 48.8 mL
