V1 ml of permanganate solution of molarity M1 reacts with V2 ml of ferrous sulphate of molarity M2 then V1M1=V2M2 5V1M1=V2M2 V1M1=5V2M2 none

Two solution of H_(2)SO_(4) of molarities x and y are mixed in the ratio of V_(1) mL : V_(2) mL to form a solution of molarity M_(1) . If they are mixed in the ratio of V_(2) mL : V_(1) mL , they form a solution of molarity M_(2) . Given V_(1)//V_(2) = (x)/(y) gt 1 and (M_(1))/(M_(2)) = (5)/(4) , then x : y is

In the titration of K_(2)Cr_(2)O_(7) and ferrous sulphate, following data is obtained: V_(1) mL of K_(2)Cr_(2)O_(7) solution of molarity M_(1) requires V_(2) mL of FeSO_(4) solution of molarity M_(2) . Which of the following relations is /are true for the above titration?

V_(1)mL of CH_(3)COONa solution (of molarity M_(1) ) and V_(2)mL of a HCl solution (of Molarity M_(2) ) are available ,Can the two be mixed to obtain a buffer solution? If Yes, what should be the mathematical condition relating M_(1),M_(2),V_(1)& V_(2) for this?

Use of dilution formula (M_(1)V_(1) = M_(2) V_(2))

When V ml of 2.2 M H_(2)SO_(4) solution is mixed with 10 V ml of water, the volume contraction of 2% take place. Calculate the molarity of diluted solution ?

A 100 ml mixture of Na_(2)CO_(3) and NaHCO_(3) is tittrated against 1 M HCl. If v_(1)L and v_(2)L are consumed when phenolphthalein and methyl orange are used as indicators respectively in two separate titrations, which of the following is true form molarities in the original solution.

80 " mL of " KMnO_4 solution reacts with 3.4 g of Na_2C_2O_4.2H_2O in acidic medium. The molarity of the KMnO_4 solution is. (a). 0.5M (b). 0.1M (c). 5M (d). 1M

Water falls from a tap with A_(0)=4 m^(2) , A=1 m^(2) and h=2 m, then velocity v is

When a body moves with velocity V_1 for first half of the journey and V_2 for remaining half of the journey, its average velocity is given by 2/V_"av"=1/V_1+1/V_2 . If V_1 and V_2 are (15pm0.5) m/s and (30pm0.1) m/s, find the average velocity within error limits.

Two balls A and B of masses m and 2 m are in motion with velocities 2v and v, respectively. Compare: Their momentum.
