How do you balance redox equations in acidic solutions?
Anuta_ua [19.1K]

Answer:

First, balance the half-reactions

Second, equalize the electrons

Third,add two reaction equations to get final answer

Explanation:

For example

H₂C₂0₄ + MnO⁻₄ ---------->CO₂+Mn²⁺

(i) Balancing the half reactions

H₂C₂O₄-------->2CO₂+2H⁺+2e⁻

5e⁻ +8H⁺+MnO₄⁻----------->Mn²⁺+4H₂O

(ii)

Equalizing the electrons

5H₂C₂O₄--------->10CO₂+10H⁺+10e⁻  ---here there is a factor of 5

10e⁻+16H⁺+2MnO₄⁻--------->2Mn²⁺+8H₂O -----here there is a factor of 2

(iii)

Add the two where electrons and some Hydrogen ions will cancel out

5H₂C₂O₄+6H⁺+2MnO₄⁻---->10CO₂+2Mn²⁺+8H₂O

What is the osmotic pressure of a 0.850 m solution of glucose in water at 35 °c?
Alik [6]

The osmotic pressure of the glucose solution is 21.49 atm.

From the question given above, the following data were obtained:

  • Molarity (M) = 0.85 M
  • Temperature (T) = 35 °C = 35 + 273 = 308 K
  • Van't Hoff's factor (i) = 1 (non-electrolyte)
  • Gas constant (R) = 0.0821 atm.L/Kmol
  • Osmotic pressure (π) =?

π = iMRT

π = 1 × 0.85 × 0.0821 × 308

π = 21.49 atm

Therefore, the osmotic pressure is 21.49 atm
