    Fehling’s solution is a deep blue alkaline solution which is used to identify the presence of aldehydes or groups that contain any aldehyde functional group -CHO and in addition with Tollen’s reagent to differentiate between reducing and non-reducing sugars.

    Molarity and Normality are related as follows:

    Normality = <nobr>MolarityX Molar mass/Equivalent mass</nobr>

    For acids the normality can be calculated with the following formula:

    Normality = Molarity x Basicity

    To know the value for basicity, count the number of H+ ions an acid molecule can give.

    For bases the normality can be calculated with the following formula:

    Normality = Molarity x Acidity

    It's alright!....just take a deep breathe and relax...have some chai and keep your mind cool. Now.....(i will only be talking about physical chem) Chemistry he sooo it neans NCERT ke jo formulae he wo acche se yaad karke apne long term memory me ghusa lo...1. pehle yaad karo. 2.paper lo pen lo and without looking at the book start writing the formulae. 3. Now yaad ho gya ho to a.intext questions karo.b.examples questions karo.c.exercise wale jo questions he na uussme tum book ko dekho and then jo formulae apply ho rhe he usko book me hi likho and then apko jisme nahi ata karna wo copy me practice karo. 4. Yayyyyy hogya. 5. I am sure yeh sab karne ke baad you will become confident. 6. Take atleast 1 and a half day to finish the work and work SMARTLY. 7. PAST PAPERS is a MUST. 8. Abhi kasht kar lo baad me rahat he.
