What are substances that release hydroxide ions or take up hydrogen ions in a solution?
Substances that release hydroxide ions in solution are called bases, while substances that take up hydrogen ions are called acids. Acids donate hydrogen ions to the solution while bases accept them. The combination of an acid and a base results in a neutralization reaction.
Is a substance that can take up hydrogen ions OR release hydroxide in water a base?
Yes, a substance that can take up hydrogen ions or release hydroxide ions in water is considered a base. Bases are characterized by their ability to accept protons or release hydroxide ions, which helps in neutralizing acids.
Why is water neutral despite to production of hydrogen ions and hydroxide ions?
Water is considered neutral because the number of hydrogen ions (H+) produced by the self-ionization of water (H2O -> H+ + OH-) is equal to the number of hydroxide ions (OH-) produced. This results in a balanced concentration of H+ and OH- ions, giving water a neutral pH of 7.
What is the process for calculating the pH of a strong acid solution?
To calculate the pH of a strong acid solution, you can use the formula pH -logH, where H represents the concentration of hydrogen ions in the solution. For a strong acid, the concentration of hydrogen ions is equal to the concentration of the acid. Simply take the negative logarithm of the hydrogen ion concentration to find the pH value.
How does the iron react when mixed with hydrochloric acid?
Acids produce hydrogen ions, H+. These ions take electrons away from iron atoms, turning them into ions, Fe++. The hydrogen is converted by this process back into its neutral atomic form, and bubbles away in the form of hydrogen gas, H2. The ionic iron remains dissolved in the aqueous solution, as part of the ferrous chloride compound.

What are the substance that can take up or release hydrogen ions into solution as hydrogen concentration of solution changes?
Substances that can take up or release hydrogen ions into solution as the hydrogen concentration changes are called buffers. Buffers help maintain the pH of a solution by accepting or donating hydrogen ions as needed. This helps prevent large fluctuations in pH when acids or bases are added to the solution.
Is a substance that can take up hydrogen ions OR release hydroxide in water a base?
Yes, a substance that can take up hydrogen ions or release hydroxide ions in water is considered a base. Bases are characterized by their ability to accept protons or release hydroxide ions, which helps in neutralizing acids.
What is the substance that accepts or binds hydrogen ions in a solution?
A substance that accepts or binds hydrogen ions in a solution is called a base. Bases have a pH above 7 and can neutralize acids by accepting hydrogen ions to form water. Examples of bases include sodium hydroxide and ammonia.

What will most likely happen if the hydrogen pump protein in photosystem it doesn't take in enough H ions into the thylakiod?
A decrease in the formation of ATP

What will most likely happen if the hydrogen pump protein in photosystem 1 doesn't take in enough h ions into the thylakoid?
there will be a decrease in the formation of NADPH.
Why is it not possible to electrolyse a solid substance?
It is not possible to electrolyze a solid substance because in order for electrolysis to occur, the substance needs to be dissolved in a liquid or molten form to allow for the movement of ions. Solids do not allow for this movement of ions required for electrolysis to take place.
Why does it take several redox reaction in a cell to make water from hydrogen and oxygen?
Without getting into the specifics of the electron transport chain, redox reactions are needed because electrons need to be shuffled around to provide the right conditions for the oxygen and hydrogen to combine. After respiration, there are many hydrogen ions (protons) sitting around while "their" electrons are being passed back and forth in continuous redox reactions. The very last redox reaction is when the electronegative oxygen accepts the electrons -- then four hydrogen ions come in to bond with O2 to make two water molecules.
