What can assemble into layers due to their charged hydrophilic heads?
phospholipids
What is Pure Water with pH 7 considered to be?
Pure water with a pH of 7 is considered to be neutral, meaning it is neither acidic nor basic. A pH of 7 indicates a balance of positively charged hydrogen ions (H+) and negatively charged hydroxide ions (OH-) in the water.
What is the midpoint of the pH scale?
The midpoint of the pH scale is pH 7, which is considered neutral. Substances with a pH lower than 7 are acidic, while substances with a pH higher than 7 are basic.
What best describes the pH number indicates about a solution?
pH is related to the activity of ions H+ in a solution. A pH under 7 is acidic, pH=7 is neutral and a pH over 7 is basic.
What is the net charge of phosphatidylserine at pH 7?
DNA molecules are connected via a 5'-3' phosphodiester linkage to ribose molecules. The phosphate group within this linkage is contains a negatively charged oxygen atom at a PH of 7. This gives DNA its charge.
What can assemble into layers due to their charged hydrophilic heads?
phospholipids
What is a molecule with a positively charged end and a negatively charged end?
its called a Zwitter ion, malic acid in pH 7 is a zwitter ion
Are low pH levels negatively charged or positively charged?
Low pH levels: cations with positive charge.
What is the impact of pH on the charge of amino acids?
The pH level affects the charge of amino acids by determining whether they are positively charged, negatively charged, or neutral. At low pH levels, amino acids tend to be positively charged, while at high pH levels, they tend to be negatively charged. This is because the pH influences the ionization of the amino acid's functional groups.
What is Pure Water with pH 7 considered to be?
Pure water with a pH of 7 is considered to be neutral, meaning it is neither acidic nor basic. A pH of 7 indicates a balance of positively charged hydrogen ions (H+) and negatively charged hydroxide ions (OH-) in the water.
Which ranges on the pH scale are acidic basic and neutral?
pH 0 < acidic < pH 7 neutral = pH 7 pH 7 < basic < pH 14
What is the pH value of calcium Iodide?
A 10% solution of calcium nitrate has a pH of about 6.0. Calcium nitrate is the primary source of water soluble calcium in hydroponics. Prolonged use in other growing media can result in a gradual increase in pH because the negatively charged nitrate ions are taken up faster than the positively charged calcium ions.
Is pH 7 a high pH?
no 7 is not a high PH. the Ph scale is out of 14 meaning 7 is neutral :)
What is acidic and alkaline in pH?
pH<7 -----> Acidic pH=7------> Neutral pH>7------>Basic or Alkaline
How are acid base and pH related?
pH<7 acid pH=7 neutral pH>7 base
What happens to the pH of a acid when it is neurtralised?
The pH of an acid will increase and it will be 7 or close to 7. pH= 7 is considered neutral and a pH under 7 is acidic and a pH above 7 is alkaline.
PH of less than 7 acids bases both or neither?
A pH of 7 is neutral. pH<7= acidic; pH>7=basic
