WebAcids, Bases and Salts are all used in photographic processing solutions. The oxides are used to make acids, bases and salts but are never used directly in photographic processing. Acids are used in stop bath and fixing solutions. Therefore, they have pH values less than 7. Bases are used in the developer. http://cafee.ase.ro/wp-content/almond-extract-hjn/qe5m5a9.php?c38aff=photo-1%3A-acid-base-reactions-well-plate how and why the skin works physiology

"WebSo it must be an exothermic reaction then. For a simple answer, an acid, likes do donate its H X + ions, and a base likes to give off its O H X − ions. The bond enthalpy of the A-H and B-OH bonds are low. Now the H X + a n d O H X − fuse to form a water molecule, giving rise to new bonds, hence is an exothermic process.

WebThe first step is to calculate moles of strong acid and moles of strong base. And the equation for molarity is equal to moles over liters. So for our strong acid, HCl, the molarity is 1.0, and the volume is 300 milliliters, which is equal to .300 liters. So solving for x, we find that x is equal to .30 moles of HCl.

WebMay 30, 2024 · First, let reactions go to completion (in the direction that makes sense, i.e. weak base and strong acid forms weak acid and spectator ion - never the other way around). Then, check what the major species are and estimate the pH.
