Because we can only measure relative potentials, so we need to designate some point as zero. Hydrogen is a pretty good choice, since that way we can tell whether a given substance will react with acids to liberate hydrogen or not just based on the sign of the half-cell potential.

City name where Pakistan Standard time is taken?
The city where Pakistan Standard Time (PST) is taken as the reference time is Karachi. Karachi is the largest and most populous city in Pakistan and serves as the country's economic and cultural hub. It is located in the southern part of Pakistan and is known for its diverse population, vibrant markets, and historical landmarks.
What happens when you put hydrogen peroxide on substances taken from most biological materials?
A violent reaction of oxydation.
Besides the earth what things have a gravitational pull?
Any object that is above the reference level (usually taken as ground level) has potential energy, according to the formula PE = mgh.Any object that is above the reference level (usually taken as ground level) has potential energy, according to the formula PE = mgh.Any object that is above the reference level (usually taken as ground level) has potential energy, according to the formula PE = mgh.Any object that is above the reference level (usually taken as ground level) has potential energy, according to the formula PE = mgh.
Does a roller coaster car have potential energy?
Yes, a roller coaster car has potential energy when it is at the top of a hill, due to its height and gravity. As the car descends, this potential energy is converted into kinetic energy as it gains speed.
Why primary cell have 1.5 V only?
It depends on the electron configuration. Different metals have single electrode potential. They are both +ve and -ve. We use standard Hydrogen electrode whose potential is taken to be 0. Using that we can find half potential. Then right from that we get the total potential of a cell. So it is all natures work
What is the purpose of a reference electrode in electrochemical measurements?
The purpose of a reference electrode in electrochemical measurements is to provide a stable and known electrical potential against which the potential of the working electrode can be measured accurately. This helps ensure the reliability and accuracy of the electrochemical measurements being taken.
Why carbon is taken as standard value for atomic weight while not others like oxygen and hydrogen?

Why water always taken as standard?
Water is not often taken as a standard in chemistry.
How often must a census be taken and what sets this standard?
A Cencus must be taken every 10 years Unknown standard
Why are the Arctic and Antarctic Circles taken as standard?
All lines of latitude are taken as standard. These lines of latitude, however, do wobble with the Earth's wobble.
What are the precautions should be taken before the collection of hydrogen gas?
Before collecting hydrogen gas, you should ensure proper ventilation to prevent the accumulation of hydrogen gas, wear appropriate personal protective equipment such as safety goggles and gloves, and ensure there are no sources of ignition nearby to prevent potential fires or explosions. It is also important to use a designated collection container and handle hydrogen gas with care to avoid leaks.
Is hydrogen used in its pure form?
Hydrogen is often used in its pure form for various applications, such as fuel cells for energy production, as a reducing agent in industrial processes, and in the semiconductor industry for manufacturing purposes. However, due to its highly flammable nature, precautions need to be taken when handling pure hydrogen to avoid potential safety hazards.
How Indian standard meridian is fixed?
The standard meridian is taken as 82'30 Degrees. It is taken because it passes near Allahabad whicf lies almost at the center of the country.
What happens to the water molecule during condensation?
A hydroxide is taken from the glucose and a hydrogen is taken from the fructose. This leaves the glucose and fructose a place to bond. A hydroxide(HO) and a hydrogen (H) make a water molecule (H2O)
What is the value of hydrogen?
Hydrogen is a versatile element with various applications, including in the production of ammonia, petroleum refining, and fuel cells for clean energy. Its value lies in its abundance, clean-burning properties, and potential to play a significant role in the transition to renewable energy sources.
What if we didn't have hydrogen?
Another element would have had to taken its place, since hydrogen is such a critical component of so many things--water, petroleum, sugars, proteins...
