Ethylene is a hydrocarbon which has the formula C ₂H ₄ or H₂C=CH₂. It is a colourless flammable gas with a faint "sweet and musky" odour when pure. It is the simplest alkene.
Ethylene is widely used in the chemical industry, and its worldwide production exceeds that of any other organic compound.
<h3>What is ethylene used for?</h3>
Medical: Ethylene is used as an anaesthetic. Metal Fabrication: Ethylene is used as oxy-fuel gas in metal cutting, welding and high velocity thermal spraying. Refining: Ethylene is used as refrigerant, especially in LNG liquefaction plants. Rubber & Plastics: Ethylene is used in the extraction of rubber.
<h3>Is ethylene harmful to humans?</h3>
* Ethylene gas can affect you when breathed in. * Skin contact with liquid Ethylene can cause frostbite. * Exposure to Ethylene can cause headache, dizziness, fatigue, lightheadedness, confusion and unconsciousness. * Ethylene is a HIGHLY FLAMMABLE and REACTIVE chemical and a DANGEROUS FIRE and EXPLOSION HAZARD.

Answer:
pH at equivalence point is 8.52
Explanation:
1 mol of HCOOH reacts with 1 mol of NaOH to produce 1 mol of 
So, moles of NaOH used to reach equivalence point equal to number of moles produced at equivalence point.
As density of water is 1g/mL, therefore molarity is equal to molality of an aqueous solution.
So, moles of produced = 
Total volume of solution at equivalence point = (25+29.80) mL = 54.80 mL
So, at equivalence point concentration of = 
At equivalence point, pH depends upon hydrolysis of . So, we have to construct an ICE table.
I: 0.1940 0 0
C: -x +x +x
E: 0.1940-x x x
So, ![\frac{[HCOOH][OH^{-}]}{[HCOO^{-}]}=K_{b}(HCOO^{-})=\frac{10^{-14}}{Ka(HCOOH)}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BHCOOH%5D%5BOH%5E%7B-%7D%5D%7D%7B%5BHCOO%5E%7B-%7D%5D%7D%3DK_%7Bb%7D%28HCOO%5E%7B-%7D%29%3D%5Cfrac%7B10%5E%7B-14%7D%7D%7BKa%28HCOOH%29%7D)
species inside third bracket represent equilibrium concentrations
So, 
or,
So, 
So, 
So, ![pH=14-pOH=14+log[OH^{-}]=14+logx=14+log(3.285\times 10^{-6})=8.52](https://tex.z-dn.net/?f=pH%3D14-pOH%3D14%2Blog%5BOH%5E%7B-%7D%5D%3D14%2Blogx%3D14%2Blog%283.285%5Ctimes%2010%5E%7B-6%7D%29%3D8.52)
It is in a large elliptical shape!
