Do bases have a high or low concentration of hydrogen ions?
Bases have a low concentration of hydrogen ions. In contrast, acids have a high concentration of hydrogen ions.
When the pH is high what is true about the concentration of hydrogen ions?
A numerically high pH , the hydrogen ions are very low . e,.g, pH 12 is a very alkaline solution. A numerically low pH , the hydrogen ions are very high . e.h. pH 2 is very acidic .
Why are acidic liquids good conductors?
Acidic liquids are good conductors due to the high concentration of hydrogen ions (H+) which can move around the liquid, carrying the electric current between the positive and negative electrodes. Acids have a low pH value and a high concentration of H+ ions.
What process that alows movement of gases and ions from areas of high consentration to low consentration?
Diffusion is the process that allows movement of gases and ions from areas of high concentration to areas of low concentration. This process is driven by a concentration gradient.
What solution has a greater concentration of hydrogen ions a pH of 7 or a pH of 3?
When the pH is low, the concentration of the hydrogen ions is high. So pH of 3 has a greater concentration of hydrogen ions.

What happens when sucrose is taken up by active transport?
Outside the cell is high concentration of hydrogen ions and low concentration of sucrose. Inside, is the opposite, low concentration of hydrogen ions, and high concentrations of sucrose. Cells use ATP to pump a hydrogen ion across the cell membrane, against the concentration gradient, and when the hydrogen ion goes to re-enter, it goes through a Sucrose-proton cotransporter. This means that the hydrogen ion (proton) take a sucrose molecule with it when it goes though the membrane.
What is the movement of ions from high concentration to low concentration?
The movement of ions from high concentration to low concentration is called diffusion. In diffusion, ions move from an area of higher concentration to an area of lower concentration until equilibrium is reached. This process occurs spontaneously and does not require an input of energy.
What does pH mean for biology?
The log to the base 10 of the concentration of Hydrogen ions (H+) in a solution times -1. pH = -log10[H+] This measures the acidity of a solution. A low pH indicates a high concentration of H+(and therefore a low concentration of OH-) which is an acidic solution, and a high pH is found in alkaline solutions (low H+ and high OH-). Neutral is 7 - the pH of water, when there are the same number of H+ ions as OH- ions.
Low pH means that the hydrogen-ion concentration is?
pH refers to hydrogen parts the lower the hydrogen parts the more acidic a substance is the higher adversely relates to how alkaline or basic a substance is it is scaled from 1-14 i being the most acidic 14 being the most basic when the pH is high, then the concentration of Hydrogen(H+) ions is low

When the pH is low, the concentration of the hydrogen ions is high. So pH of 3 has a greater concentration of hydrogen ions.

When the pH of solution is low is the concentration of hydrogen ions high or low?
pH refers to hydrogen parts the lower the hydrogen parts the more acidic a substance is the higher adverseley relates to how alkaline or basic a substance is it is scaled from 1-14 i being the most acidic 14 being the most basic. pH low -> [H+] high
Can you have a high concentration of a weak acid?
An electrolyte is said to be concentrated, in a solution which has high concentration of ions. It is said to be dilute in a low concentration of ions solution. The electrolyte is strong, if a high proportion of the solute dissociates to form free ions. The electrolyte is weak, if most of the solute does not dissociate.
