Why is standard hydrogen electrode called reversible electrode?
Depending on the other cell used, it can turn H+ ions into hydrogen gas, or it can turn hydrogen gas into H+ ions. Thus it is reversible.
What is the color of the FeSCN plus 2 complex ion?
red.
Is energy required or released in the formation of negative ions?
ergy is released in the formation of negative ion
Does energy always released during ionization?
During the formation of anions (negatigely charged ions) energy is released. During the formation of cations (positively charged ions) energy is absorbed.
What is the heat of formation of n2O4?
The heat of formation of zinc nitrate is -2304 kJ.
How can potassium thiocyanate be used to confirm that fe2 plus ions have been oxidized to fe3 plus?
Fe^3+ ion forms the complex with SCN- , forming [FeSCN]2+
Why is standard hydrogen electrode called reversible electrode?
Depending on the other cell used, it can turn H+ ions into hydrogen gas, or it can turn hydrogen gas into H+ ions. Thus it is reversible.
What is the Kc value for FeSCN?
215 to 300
What is the color of the FeSCN plus 2 complex ion?
red.
Is energy required or released in the formation of negative ions?
ergy is released in the formation of negative ion
What is dissociation of water mean?
This is the formation of the ions H+ and OH-.
What is the formation of ions when a solvent acts on a solute?
i think its ionization
What mechanism causes stomates to open when the guard cells are in good conditions?
The reversible uptake and loss of potassium ions (K+)
Does energy always released during ionization?
During the formation of anions (negatigely charged ions) energy is released. During the formation of cations (positively charged ions) energy is absorbed.
Does the acide or alkaline increase rusting?
Rust formation is accelerated in the presence of acid. One of the byproducts of rust is the formation of hydroxide ions. Acid neutralises these ions allowing more to form.
Why formation of ADP from ATP release more energy then formation of AMP from ADP?
20 ions are broken down
What is the importance of ionzation energy in the formation of ions?
The meaning of a high ionization energy is that the formation of an ion is more difficult.
