Define the unit of radioactivity, Curie (Ci) and Becquerel (Bq). Calculate the
strength of 9.6 ng of 198Au (t1/2 = 2.7 d) in Curie.
The Curie (Ci) and the Becquerel (Bq) are units of radioactivity used to measure the activity of radioactive substances. These units provide different ways of quantifying the rate at which a radioactive material undergoes decay.
1. Curie (Ci):
The Curie (Ci) is a traditional unit of radioactivity. It was named in honor of Pierre Curie and Marie Curie, who made significant contributions to the field of radioactivity. One Curie is defined as the activity of one gram of radium-226 (Ra-226),

A solution of Zn is electrolysed for 30 s using a current if 1.0 mA. Calculate the mass of Zn plated on the electrode for the electrochemical reaction: Zn2+ + 2e ï‚® Zn
An impure sample of CaC2O4H2O is analysed using TGA technique. TG curve of the sample indicates the total mass change from 85 mg to 30.7 mg when this sample was heated upto 1173 K. calculate the purity of the sample
What are the characteristics of a reference electrode? Describe the construction
and working of a Calomel electrode
What is the cell potential of an electrochemical cell made of a cadmium electrode in a 0.1 M Cd(NO3)2 solution and chromium electrode in a 1 × 10−4 M Cr(NO3)3 solution.
To analyse a brass alloy, a 0.442 g sample is dissolved in acid to volume in a
500 cm3 volumetric flask. Electrolysis of a 10 cm3 sample at − 0.3 V vs. SCE
reduces Cu2+ to Cu, requiring total charge of 16.11 C. Adjusting the potential of
0.6 V vs. SCE and completing the electrolysis requires 0.442 C to reduce Pb2+ to Pb. Report
the percentage of Cu and Pb in the alloy.
