Solutes that dissociate in water and forms ions are electrolytes. Strong acids and bases in an aqueous solution form a strong electrolyte, which can dissolve completely as a soluble item. Weak electrolytes do not completely dissociate and are usually weak acids and bases. Since strong electrolytes ...

To find the pOH of the given aqueous solution, we will follow these steps:Step 1: Calculate the OH⁻ concentration We know that the ionic product constant of water (Kw) is given by the formula:\( Kw = (H^+)(OH^-) \)
What is the molarity of an aqueous solution containing 43.7 g of glucose (C_6H_{12}O_6) in 1.1 L of solution? A 650.0 mL solution contains 125 grams of glucose. If the molar mass of C_6H_{12}O_6 is 180.16 g/mol, what ...
What is the pH of an aqueous solution with a hydrogen ion concentration ofH+= 6.7 * 10-9 M? pH of a solution: The pH of a solution is equal to the negative logarithm of the concentration of proton in aqueous solution: {eq}pH = -\log [H^+] {/eq} ...

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...
What makes water such a good solvent? Water is a good solvent due to its polarity. The solvent properties of water are vital in biology, because many biochemical reactions take place only within aqueous solutions When an ionic or polar compound enters water, it is surrounded by water molecules...
