chemistry practical

14.5.20
Day 4
Good Morning Boys,
Today you will write the experiment for the detection of Bromide and Iodide radical present in the inorganic salt.

Learning Outcomes :
Students will be able to
  • Identify bromide and Iodide Radical
  • Learn the test of acid Radical
  • Differentiate the two radical on the basis of chemical test.
Refer to the images to write the practical, related to detection of  Bromide and Iodide Radical.




THATS ALL FOR THE DAY

Definations and molecular mass calculation

Day 1         4th period 21. 4.20 FOR MARKING YOUR ATTENDANCE TYPE YOUR NAME AS PER THE DIRECTIVES GIVEN BELOW ⇓ AND CLICK SUBMIT. Loading… GOOD MORNING BOYS, Today we will be going through the various definations and calculate the molecular masses of compound. Learning objective : students will be able to Define atomic mass, Molecular Mass & formula mass calculate molecular masses of compounds. Atomic mass unit   It is defined as a mass exactly equal to one twelfth the mass of one carbon – 12 atom. Gram atomic mass of a substance  –   The atomic mass of a substance when expressed in grams is known as its gram atomic mass. The atomic mass of Sulphur is 32u. Gram atomic mass of Sulphur is 32g .   Molecular mass It is the sum of atomic masses of the elements present in a molecule.  It is obtained by multiplying the atomic mass of each element by the number of its atoms and  adding them ...

Chemistry Practical 11 D

Day 4 18.4.20 Good Morning students:  Today is our first chemistry practical period through blogs. please read the general instruction carefully. General Instructions :  1. students must get the concern slip signed by the parents for working in the laboratory. The concern slip contains the guidelines for working in the laboratary. Written guidelines for working in chemistry lab would be given once the school reopen. kindly note signature of  parent on concern slip is mandatory for working in chemistry lab. 2. Labcoat is mandatory for working in the lab. 3. carry your practical file and stationary during the practical period. 4. Follow the Instruction given by teacher at all times. 5. Casual attitude while working in lab will not be entertained. 6. Class would be divided into 2 batches: Batch 1 Physics Batch 2 chemistry (depending on the strength of class ) At present both the batches would be writing the practical in your chemistry file. The p...

NUMERICAL PRACTICE

DAY 5 27.4.20 Good Morning Boys, Today we will be practising the numericals related to the concept learnt in previous classes. Learning outcome : students will be able to Apply the formula interpret the question. Analyse the question. Molarity formula with  Density  is given as conversion table for reference : 1 cm 3 1mL 1000 mm 3 1 Litre 1000mL 1000 cm 3 1 m 3 10 6   cm 3 1000 L 1 dm 3 1000 cm 3 1 L NUMERICAL QUESTIONS : Question 1 Calculate the molarity of  N a O H N a O H  in the solution prepared by dissolving its 4 g in enough water to form 250 mL of the solution. Solution  Molarity M = Moles of solute(g)/ volume of solution (litres) = (4 g / 40 g ) ×  (1000/250) =0.1 mol/0.250 L = 0.4 mol/L = 0.4 M Question 2 20% (w/W) NaOH solution (density of solution= 1.2 g/cc). Calculate the Molarity? Solution 20% (w/M) means 20 gm  in 100gm  of solution Now Density of solution =1.2g/cc Density = mass /...
