H2SO4 is acid , when water is added to the acid it will
produce high energy , it is in the form of heat.So from this
we could not add water directly, we have to add it slowly
then we will neutralize the heat.

Answer / dinesh patil

Sulphuric acid has hydroscopic (Affinity towards water)
property. When we add water to acid due to hydroscopic
property it may suddenly comes out & may cause burning.

While mixing water & sulphuric acid we should always add
acid in water (with glass rod) & not to add water in acid.

Heat is genrated called as heat of neuterization which has
no relation with the addition

Answer / gopesh

Actually when water is added to sulphuric acid, a huge
amount of heat generates liable to crack the beaker
this is why when we need to dilute H2SO4 we take water in
a beaker and add acid slowly so that heat generation is
slow .

Answer / harsh

Since, acid is more viscous than water if we add water to
acid mixing will not be proper & thereby heat dissipation
becomes difficult. The added water takes away the
dissipated heat rapidly forming steam & creating a Flashing
or Explosion. Therefore water shouldn't be added to acid
and acid should be added to water for the dilution purpose.

Answer / sania

because on dilution of acid more amount of heat generate
which is harmful for human so water is not directly added to
acid

Answer / murthy

if water is added directly into large amount of H2so4, due
to heat of misibility water is vaporized, water required to
dilute greatly increases approximately 15-20 times .that is
why H2so4 is added to water and water is not added to h2so4.

Answer / sanjay kumar it-bhu

H2SO4 is highly acidic , when water is added to the acid it
will produce high quantiy of energy , it becomes violent
condition means break the beaker.So its dangerous for humen
so there should not be add water directly, we have to add
it slowly in dropwise manner then we will neutralize the
heat.

Answer / priyank sompura

because it is very concentrated so that for concentration
water is not directly used

QUANTUM COMPUTING - EXAMPLE 32.3 : A system of linear congruences consists of 3 equations : X ≡ 1 (mod 3), X ≡ 3 (mod 5), X ≡ 4 (mod 6). X has positive values. (a) List the values of these equations from 1 to 35. Then find the minimum value of X. (b)(i) Find the least common multiple (LCM) of b = 3, 5 and 6 where X ≡ a (mod b). (ii) If b - a has the same value of all equations above, then X + (b - a) is divisible by LCM. Find the value of minimum value of X via LCM division.

Question 69 - A well delivers 225 US-gallons per minute of water to a chemical plant during normal system operation. (a) Calculate its flowrate in the unit of mega US-gallon per day or MGD. (b) The following formula is written next to the chlorine feed point : (chlorine feed rate, lb / day) = (flowrate, MGD) X (dose, mg / L) x (8.34). If this formula is correct, then what should the chlorine feed rate to be in pounds per day (lb / day) if the desired dose is 2 mg / L. (c) Prove by calculations that the constant 8.34 in the formula next to the chlorine feed point is correct. Let 1 US-gallon = 3.78541 L and 1 mg = 0.0000022046 pound.

(a) Find the mole ratio of carbon dioxide and nitrogen gases at inlet and outlet gas streams. (b) The Henry’s Law provides y = 1640 x for carbon dioxide in water. Find the mole ratio when x = 0.0000427. Mole ratio is y / (1 - y) for y.
