Weak bases do not completely ionize in water. Therefore, to calculate the pH, the equilibrium expression must be written: {eq}K_b = \dfrac{[X^+][OH^-]}{[XOH]} {/eq} From there, the hydroxide concentration can be calculated, which can then...
What ions are found in hard water?The hardness of Water:The hardness of water can be determined quantitatively using EDTA titration. This is a complexometric titration in which the titrant is the solution with a known concentration of EDTA. Since this is a strong complexing agent, we can ...
Often referred to as a continuous UPS, double-conversion UPS systems continuously converts incoming power in real time, ensuring a consistent, uninterrupted power supply regardless of fluctuations and failures. The result is an environment that's completely isolated from power anomalies, which is ideal...
Ionization constant is a mathematical constant that's used in chemistry to measure the acidity or basicity of a solution. Most...
You can view a total solar eclipse with your bare eyes, but only when the moon completely covers the face of the sun. And if you're really gung ho about looking up at the sun without special spectacles, you could watch the event's progression through a pinhole camera. Otherwise, NASA ...
Hydrogen sulfide gas, H2S, behaves in similar fashion. Although weak, it too is a diprotic acid, which dissolved in water ionizes in two steps. The first step produces hydrosulfide ions: H2O + H2S → (H3O)+1+ (HS)-1. Step two is the further breakdown, H2O + (HS)-1→ (H3O)+1...
only slightly in water, while strong acids and bases ionize almost completely. When excess hydrogen ions are in the buffer solution, the weak base gobbles up the hydrogen ions and changes into its corresponding acid while preserving the pH of the solution. When a base is added, the reaction...

Ionize Describe a transition from a non-ionic to an ionic state. The compound ionizes easily when dissolved in water. 10 Unionized Refer to materials that do not exhibit ionic properties. Unionized particles pass through the filter, while ions are trapped. 7 Ionize Convert an atom or molecule...
(chemistry) That completely ionizes into anions and cations in a solution. A strong acid; A strong base Strong (military) Not easily subdued or taken. A strong position Strong Having wealth or resources. A strong economy Strong Impressive, good. You're working with troubled youth in your off...
