What makes a substance a base? The pH scale: The pH scale is the scale used to measure whether a substance is acidic or basic. This largely depends on the number of hydrogen ions that the substance contains. The lower on the scale that a substance is, the more acidic it is, and the...
Which hydrogen in each molecule is most acidic? Which of the following acids will have the strongest conjugate base? A) H C l B) H C l O 4 C) H N O 3 D) H 3 P O 4 E) H I What makes a substance a base? What is the conjugate acid and base of SH-1?
If the pKbordissociation constantof an alkaline substance has a high enough value, the basic substance will dissociate into its component ions in aqueous solution even when the pH is already strongly basic (i.e. pH of about 12 or higher). The pH scale technically goes higher than 14.0, but...
In determining the ionization constant of a weak acid, the concentrations of the two ionic components of the acid are multiplied, and the product is then divided by the concentration of the molecular acid in solution. For example, with acetic acid, the concentration of hydronium ions would be ...
Its adaptability and usefulness make it an important instrument for farmers who want maximum crops, as well as supporting environmentally friendly agriculture. In this article, we will take a closer look at the uses of anhydrous ammonia in agriculture. This versatile substance is used for fertilizati...
Consideration of some practical examples, such as wastewater treatment, can make the guidelines more clear. A brief refresher on pH pH is defined as the negative logarithm of molar concentration of hydrogen ions in a solution: pH = -log ([H+]) (1) A ...
and one atom of hydrogen. The arrangement of its molecules in a linear pattern makes it a polar molecule due to the presence of negative and positive ions. However, its weak bonds make it unstable, disintegrating into gaseous fragments within seconds. Therefore, it requires extremely cold storage...
Copper sulfate, also known as cupric sulfate or blue vitriol, is a chemical compound with the formula CuSO4. It is a salt that is highly soluble in water and has a blue color due to the presence of copper ions. Copper sulfate is commonly used as a fungicide, herbicide, and pesticide in...
What substance has an equal number of hydrogen ions and hydroxide ions? Which of the following contributes to global warming? a. nitrogen b. carbon dioxide c. helium d. chlorine Fill in the blanks with correct word/s. When a substance does not have an affinity for water or it is "wa...
pH measures the concentration of H+ and Hydroxide (OH-) ions that make up water (H2O): 1H+ + 1OH- = H2O. If the two ions are of equal concentration, they form water, which is neutral. However, if H+ is greater than OH-, the substance is acidic, and otherwise, it’s basic. ...
