Matt needs a suggestion to test the nature of solution besides it's taste and corrosiveness. What suggestion would you recommend

grandymaker [24]

A solution with pH less than 7 is acidic while that with a pH greater than 7 is alkaline. So, in order to test the nature of solution( whether acidic or basic) we would use a litmus paper. Litmus paper contains a pH sensitive dye which is red colored in acidic form and blue colored in basic form. Acidic solution turns blue litmus paper red. Alkaline solutions turn red litmus paper blue. Hence, the nature of solution can be detected by using litmus paper test.

a flask was filled with SO2 at a partial pressure of 0.409 atm and O2 at a partial pressure of 0.601 atm. The following gas-phas

jarptica [38.1K]

Answer:

The equilibrium partial pressure of O2 is 0.545 atm

Explanation:

Step 1: Data given

Partial pressure of SO2 = 0.409 atm

Partial pressure of O2 = 0.601 atm

At equilibrium, the partial pressure of SO2 was 0.297 atm.

Step 2: The balanced equation

2SO2 + O2 ⇆ 2SO3

Step 3: The initial pressure

pSO2 = 0.409 atm

pO2 = 0.601 atm

pSO3 = 0 atm

Step 4: Calculate the pressure at the equilibrium

pSO2 = 0.409 - 2X atm

pO2 = 0.601 - X atm

pSO3 = 2X

pSO2 = 0.409 - 2X atm = 0.297

X = 0.056 atm

pO2 = 0.601 - 0.056 = 0.545 atm

pSO3 = 2*0.056 = 0.112 atm

Step 5: Calculate Kp

Kp = (pSO3)²/((pO2)*(pSO2)²)

Kp = (0.112²) / (0.545 * 0.297²)

Kp = 0.261

The equilibrium partial pressure of O2 is 0.545 atm
