What are acids and bases in biology quizlet?
An acid is and ionic compound that produces positive hydrogen ions when dissolved in water, while bases are an ionic compound that produces negative hydroxide ions when dissolved in water.
What makes a solution acidic or basic quizlet?
Acidic solutions are any solution that has a higher concentration of hydrogen ions than water; solutions that have a lower concentration of hydrogen ions An alkaline solution is one that is a pH higher than 7.0.
What is a basic solution quizlet?
Basic Solution. A liquid mixture that has a pH level greater than 7, which typically means there are a greater number of hydroxide ions than hydrogen ions. Conjugate Acid.
What is an acid in biology quizlet?
acid. a compound that forms hydrogen ions (H+) in solution and measures less than 7 on the pH scale. base. a compound that produces hydroxide ions (OH-) in solution and measures more than 7 on the pH scale. buffer.
What is the difference between an acid and a base?
An acid is any hydrogen-containing substance that is capable of donating a proton (hydrogen ion) to another substance. A base is a molecule or ion able to accept a hydrogen ion from an acid.
What is a base in biology?
In nucleic acid chemistry, one of the nitrogenous compounds, i.e. purines and pyrimidines, that are incorporated into nucleosides, nucleotides and nucleic acids. The most common bases are adenine, cytosine, guanine, thymine and uracil, abbreviated as A, C, G, T and U respectively. Tags: Molecular Biology.
What is defined as an acidic solution?
An acidic solution has a high concentration of hydrogen ions (H +start superscript, plus, end superscript), greater than that of pure water. A basic solution has a low H +start superscript, plus, end superscript concentration, less than that of pure water.
Which is a condition of an acid solution?
A solution with a pH less than 7 is considered acidic, and a solution with a pH greater than 7 is considered basic, or alkaline. Strong acids have a higher concentration of hydrogen ions, and they are assigned values closer to 0.
What is the pH range of a basic solution quizlet?
Ranges from 0 (acidic) to 14 (basic/alkaline), with 7 being neutral. You just studied 9 terms!
What makes an acid different from a base?
An acid is any hydrogen-containing substance that is capable of donating a proton (hydrogen ion) to another substance. A base is a molecule or ion able to accept a hydrogen ion from an acid. Acidic substances are usually identified by their sour taste.
What are three differences between acids and bases?
(i) Acids are sour to taste. Bases are bitter to taste. (ii) Acids turn blue litmus red. Bases do not change the colour of blue litmus.
What is the difference between an acid and a base give an example of each?
Differences Between Acid and Base An acid is a proton donor. While a base is a proton acceptor. Acetic acid (CH3COOH) and sulphuric acid are two examples of Acid. Sodium Hydroxide (NaOH) and Ammonia are two examples of Bases.
