To determine the pH of an aqueous solution (that is, a substance dissolved in water), you need to only know the concentration of hydrogen ions (H+) in that solution, or its molarity. But apart from pH, what are moles, molarity and acids all about, anyway? Molar Mass Calculator Common...
Staying hydrated isn’t just about keeping thirst at bay – water is essential for the human body to function, transporting nutrients and oxygen around the body. It’s also important for your mind, with even the smallest amount of dehydration leading to impaired concentration and alertness, ...
This review mainly aimed to introduce the findings of research projects comparing the responses of tropical and temperate indigenes to heat. From a questionnaire survey on thermal sensation and comfort of Indonesians and Japanese, we found that the thermal descriptor “cool” in tropical indigenes con...
Another measured memory and concentration, asking players to remember and repeat increasingly long sequences of numbers. Other games registered how generous and trusting (or skeptical) applicants might be, giving them more fake money and asking whether they wanted to share any with virtual partners....
To calculate the pH of a buffer, we write the equation of the aqueous solution of the acid in equilibrium with its conjugate base: $$HNO_{2}+H_{2}O\rightleftharpoons H_{3}O^{+}+NO_{2}^{-} $$ Step 3: Determine the concentration of the conjugate acid and base In this ...
How do I calculate the concentration of a weak base from PH « on: December 03, 2019, 04:36:04 AM » Hello everyone, I have to calculate the concentration of Diethylammine (Kb 8.6 10^-4) only knowing the PH of the solution, which is 8.2How do I do it? I tried to doC= ...
From this perspective, it would be interesting to explore whether this violation can be made parametrically large with increasing Zn concentration - approaching the point at which Tc → 0. Electron-phonon superconductivity: bound on T c/ω 0?
Such a strong hydrogen removal effect can be attributed to: (1) outgassing of hydrogen from the liquid iron to the argon-filled furnace chamber, where the driving force comes from the difference in hydrogen concentration between liquid iron and the gas phase38; (2) removal of the relevant ...
"If you are working in marketing with a strong background in content creation and communication, but want to get up to snuff in analytics, an MBA with a concentration in analytics will make you that much more marketable," she says. "Finally if you currently are stuck in a desk job that...
Briefly state how pH, temperature, and sucrose concentration affect sucrase activity. Another way to affect the enzyme is by lowering the pH of the solution. However, lactase is supposed to be able to work in the stomach. Would lowering the pH of the enzyme solution affect the enzyme?
