Is it true that plant roots produce weak acids that dissolves rocks?
Yes, plants roots release weak organic acids that can help dissolve minerals in rocks. This process, known as rhizosphere acidification, can contribute to the weathering of rocks and release of nutrients that plants can then absorb.
What nitrogenous organic molecule can function as a biological buffer in cells and tissues?
Amino acids, such as histidine or glycine, can function as biological buffers in cells and tissues. These molecules can act as both weak acids and weak bases, helping to maintain stable pH levels within biological systems.
Why are women weak?
Women, on the contrary are not weak. They may have less muscle mass than men do, and have a harder time building muscle mass because they do not have as many steroid-type hormones as men, but for their size, they are actually pretty strong.
What is the universal force that acts on the protons and neutrons of an atom?
The strong nuclear force acts only on neutrons and protons in the nucleus of an atom. The opposite would be a weak nuclear force.
Why do cells need protein to function?
Cells need proteins to perform essential functions such as cell structure, energy metabolism, signaling, and transport of molecules. Proteins also play roles in enzyme activity, gene expression, and immune responses. Overall, proteins are crucial for the proper functioning and maintenance of cells in living organisms.
What is true about weak acids as compared to strong acids?
Weak acids have a larger value of pKa than strong acids
What are the differences in properties and behavior between a weak acid and a strong acid?
Weak acids and strong acids differ in their properties and behavior. Weak acids partially dissociate in water, while strong acids fully dissociate. This means weak acids have lower conductivity and pH compared to strong acids. Additionally, weak acids have higher equilibrium constants and are less reactive than strong acids.
Are peptide bonds strong or weak?
Peptide bonds are strong covalent bonds that link amino acids in proteins. They have a characteristic double-bond character that gives them stability, making them vital for the structure and function of proteins.
What information can be found in the weak and strong acids and bases chart?
The weak and strong acids and bases chart provides information on the strength of different acids and bases. It indicates which substances are considered weak or strong based on their ability to donate or accept protons. This chart helps in understanding the reactivity and properties of various acids and bases.
Are acids used strong or weak?
acids are of types.....concentrated acids are strong.
Which has a lower pH weak acids or strong acids?
strong acid
What is the difference a weak and a strong acid involves the acid ability to do what?
The acids ability to disassociate completely in solution. Strong acids do and weak acids do not.
Is washing up liquid a weak or strong alkali?
it is weak and strong because it neutralises acids. So its strong not weak but weak not strong.
Are organic acid weak or strong?
Organic acids are generally weak acids. They do not fully dissociate in water, resulting in a reversible reaction that generates both the acid and its conjugate base. This characteristic distinguishes them from strong acids that completely dissociate in water.
Do strong acids have more or fewer ions than weak acids?
Strong acids have more ions in solution than weak acids because they completely dissociate into ions when dissolved in water, while weak acids only partially dissociate. This results in a higher concentration of ions for strong acids.
When weak acids react with strong acids?
When weak acids react with strong acids, the strong acid will donate a proton to the weak acid, resulting in the weak acid being protonated. This protonation increases the concentration of the weak acid cation. The conjugate base of the weak acid is formed as a result.
Can strong and weak acids and strong and weak bases be determined by using an indicator?
yes
