Kya pagalcodi hai

[@STAR-wl6zn]

Because pure water is poor conductor of electricity therefore salt is added So now Water can conduct electricity easily and NaCl act as a electrolyte which use in process of electrolysis Cathode - hydrogen Anode - Oxygen

CAN YOU EXPLAIN ME WHY HYDROGEN IS EVOLVED IN CATHODE AND WHY OXYGEN IS EVOLVED IN ANODE???

[@MathematicalGalaxy]

​@@anubhavgupta5200hydrogen forms positively charged ions so it accumulates near cathode whereas oxygen forms negatively charged ions so it accumulates near anode.

At cathode : hydrogen At anode : oxygen 😊😊 Salt : for rapid conduct the electricity to water .

Salt is added to enhance the rate of electrolysis Cathode H2 Anode O2

[@AnuradhaTyagi_]

Salt was added to make the water a good conductor / basically to add ions into the water, anode is connected to the positive terminal of battery and cathode is connected to the negative terminal of battery. Salt is NaCl (sodium chloride) Na+ being the positive ion it will be attracted by cathode (connected to negative terminal) and Cl- being negative it will be attracted by anode (connected to positive terminal.

[@Jes.terrr_03]

Ans :- 1. Because, pure water is bad conductor of electricity and water is neutral that's why salt 🧂 is added to increase the electrical conductivity of water 🌊. 2. Cathode is Hydrogen gas and Anode is Oxygen gas .

[@mukeshkumarswarnkar5468]

NaCl added to water to increase the conductivity of water and gas evolved at anode is oxygen and gas evolved as cathode is hydrogen.... 🙂🙂

to conduct electricity we need to add some minarals in water.cathod :-H+ and anode:-OH-

[@smas8664]

Sir this process is also known as chloralkali process in which NaCl is added to H2O to give NaOH+H2+Cl2 in anod cl2 and in cathod H2 and near to cathod NaOH

[@user-pk4kc5xf6e]

No bro chlor alkali process concentrated salt solution mai hota hai yaha pe NaCl ko water ki conductivity increase karne ke liye dala gaya hai yaha pe chlor alkali bhi hoga but Chlorine and NaOH negligible amount mai obtain karenge H2 and O2 main products hain and chlorine and NaOH in trace amount

[@user-oc1nj8fv7t]

1. To make the pure water, a good conductor of electricity. 2. cathode(-) :- O2 Anode (+) :- H In which, the volume of hydrogen is more than that of oxygen

[@karameattar6237]

Water is an insulator, so to make it conductor salt was added At anode- Oxygen (-ve) At cathode - Hydrogen (+ve) Trick - cathode contains alphabet H so, hydrogen Anode and oxygen don't have H so we can remember through this Although remember concept also...

Salt is added for ionic mov. Due to which electricity can pass through water and at cathode hydrogen and at anode oxygen

[@swift8743]

Salt was added to water so that slightly negative oxygen of polar water pulls positive sodium and slightly positive hydrogen of polar water pulls chlorine thus making free ions to conduct electricity.

[@riyap8028]

1. Because water has a very small amount of ion, where salt or NaCl is a strong electrolyte.For this cause, salt was added with water for electrolysis. Cathode: Hydrogen Anode:Oxygen

[@salacia7]

1. To increase the conductivity 2. Cathode- hydrogen Anode- oxygen

[@user-ye9yg8lj1d]

Anode=cl2 Cathode =h2 To make the brine such that the process of electrolysis can take place by attraction and repulsion of positive and negative ions of nacl

[@gauravmehrotra6315]

Pure or distilled water is poor conductor of electricity. When we'll add salt to it, it starts to conduct electricity because electricity can only be conducted if the desired water is a solution of acid, base or salt. Also, any base, acid or salt which has been added to water is called an electrolyte. In this case, Nacl is the electrolyte. Hope this helps!! :-)

[@masrataziz1933]

[@TheArtsCafee]

[@akshitasinnarkar9335]

A.) Salt is a ionic compound , when it is dissolved in water it gives ions na+ nd cl- , movement of ions in water will facilitate conduction of electricity . hence adding salt makes water a good conductor of electricity B.)cathode - hydrogen gas , anode - oxygen gas

[@ravindrasharma138]

Pure Water is not good conductor of electricity. Therefore, NaCl is added to it such that NaCl ionised in the water to conduct electricity. And the reaction will take place much faster
