Passage - 1
Solution is the homogenous mixture of two or more compound. The concentration of solution can be determined by the term Molarity, Molality, Mole fraction etc. Some other terms can also be derived like Molarity equation, it can be represented as.
M1V1=M2V2 or M1V1/n1=M2V2/n2
Where n1 and n2 are moles of reactant 1 and 2 respectively
For exact neutralization of Va ml of an acid having molarity Ma and basicity na by Vb ml of a base having molarity Mb and acidity nb
naMaVa = nbMbVb
on the basis of above passage answer the following question:-
51. To neutralize 100 ml 0.1 M H2SO4, NaOH required is… *
0.5 gm
0.8 gm
52. What is the concentration of nitrate ions if equal volume of 0.1 M AgNO3 and 0.1 M NaCl are mixed together? *
0.05 M
0.5 M
53. KMnO4 reacts with oxalic acid ,here 20 ml of 0.1 M KMnO4 is equivalent to… *
20 ml of 0.5 M oxalic acid
20 ml of 0.1 M oxalic acid
50 ml of 0.5 M oxalic acid
50 ml of 0.1 M oxalic acid
