Consider the titration of 100.0 ml of 0.010 0 m ce in i m hcio, by 0.040 0 m cu' to give ce and cu, using pt and saturated ag | agcl electrodes to find the end poin. (a) write a balanced titration reaction. (b) write two different half-reactions for the indicator electrode. (c) write two different nernst equations for the cell voltage. (d) calculate e at the following volumes of cu: 1.00, 12.5, 24s 25.0, 25.5, 30.0, and 50.0 ml. sketch the titration curve.

d = 0.98 g/L

Explanation:

Given data:

Density of acetylene = ?

Pressure = 0.910 atm

Temperature = 20°C (20+273 = 293 K)

Solution:

Formula:

PM = dRT

R = general gas constant = 0.0821 atm.L/mol.K

M = molecular mass = 26.04 g/mol

0.910 atm × 26.04 g/mol = d × 0.0821 atm.L/mol.K×293 K

23.7  atm.g/mol = d × 24.1 atm.L/mol

d = 23.7  atm.g/mol / 24.1 atm.L/mol

d = 0.98 g/L
