Purity Test of Sugar of Milk (Experiment in Homeopathic Pharmacy)

-

Purity test of Sugar of Milk

Requirement :

Test tube, test tube holder, test tube rack, labeling materials (pen, paper, scissors, gum). 

Reagent :

Litmus paper (red and blue), Iodine solution.  

Ingredients:

Sugar of milk and purified water .

Procedure:

Experiment 1:

Some amount of sugar of milk is taken in the fingers and is poured on the tongue.

Observation :

Colour: milky white
Smell: Odorless
Taste: Faintly sweet
Feeling in touch: Crystalline powder 

Inference :

May be pure.

Experiment 2:

Some amount of sugar of milk is taken in a clean test tube. Then, 5 times of its (sugar of milk taken test tube) bulk of water is mixed with it. Then gentle shaking is done until the sugar of milk is fully dissolve. 

Observation :

Clear odorless solution without any sediment is formed.

Inference :

May be pure.

Experiment 3:

Litmus Test:
Some amount of sugar of milk is taken in a clean test tube. Sufficient amount of water is mixed with it to make a solution.

(a) A blue litmus paper is dipped into the solution.

(b) A red litmus paper is dipped into the solution. 

Observation :

(a) The colour of blue litmus paper is not changed.

(b) The colour of red litmus paper is not changed.

Inference :

(a) Absence of Acid.

(b) Absence of alkali.

Experiment 4:

Iodine Test:
Some amount of sugar of milk is taken in a clean test tube  and sufficient amount of purified water is mixed with it to make a solution. Few drops of iodine solution is added to the solution.

Observation :

No blue colour is noticed.

Inference :

Absence of starch.

Conclusion :

Supplied sugar of milk is pure.

KNOW ABOUT BASIC ELECTRICAL AND ELECTRONIC DEVICES

Nowadays, we are familiar with the, electricity and various electrical instruments. There are many things  e.g light, fan, TV, refrigerator,switch,fuse etc. in our house. We use this instruments. But we frequently listen some terms and devices name viz. voltage, current, AC Current, DC Current, resistor, transformer, capacitor, LED, inductor etc . which we don't use these directly. But, amazing fact is that, the instruments which we daily use, are made of these(resistor, capacitor etc.).  Let's discuss these. Here, I don't discuss these so deeply. What is Voltage? and  What is Current? Voltage( Potential difference) represents the force. And Current represents the flow of electrons in the circuit. We (who are the basic users or novice) need not know much about this. It is a image of mobile charger.See what is written as input and output The unit of voltage is volt ( v ) and current is ampere ( A ). 1mA=(1/1000) A You obviously heard the term w

FUNCTION OF BASS, TREBLE, VOLUME OPTION IN AN AMPLIFIER

-
Image
Bass and Treble options are used to regulate the sound on the basis of frequency.  Generally a audio amplifier has 3 main controlling options. (i) Volume or Master  (ii) Bass (iii) Treble Volume : When we increase Volume the loudness of the audio is increased. In frequency level, the amplitude of all the frequencies are increased.  Similarly, when we decrease Volume, the loudness is decreased i.e. amplitude of all the frequencies are decreased. Bass : When we increase Bass, the loudness of only lower frequencies are increased i.e. amplitude of the lower frequencies are increased. When we decrease Bass, the loudness of only lower frequencies are decreased i.e. amplitude of the lower frequencies are decreased. Treble : When we increase / decrease the Treble, the loudness of the sound of only higher frequencies are increased / decreased. Now the main questions is that what do lower and higher frequencies mean ? We know that human beings able to hear in the fre

MATTER AND ITS STATES (PHASE)

-
Image
What is Matter: Matter is anything that has mass and occupy space. Example: wood,water,Oxygen etc. All tangible things are made of matter. How many states (phases) can a matter have in nature: There are normally 3 states. Solid, liquid and gas. There exists another one, named Plasma state. In this post, this state is not described.  Every matter can be converted from any state to any state. Suppose, water. Water can be got as solid, liquid, or gas. We know solid form of water is called ice, liquid form is water , and gaseous form is  water vapor.    How can the state of matter be changed: The changing of the state of matter is known as Phase change of matter. We can change the state of a matter Varying the Pressure Varying the Temperature  1.Changing of phase by varying Pressure: Increasing the pressure, gas can be converted into liquid and then solid. Similarly, solid can be converted into liquid and then gas. Match lighter You may
