71K Learn about acid-base indicators. Understand what acid-base indicators are, how they work to determine if a solution is acidic or basic, and see the examples. Related to this QuestionWhat is the function of the indicator phenolphthalein? Explain the purpose of adding excess hydroxide compa...
We know phenol shows acidic nature. 2,4,6-Trinitrophenol is highly acidic in nature as three electron withdrawing groups (Nitro group) are attached to it. These electron withdrawing groups on phenol make it highly acidic. That's why it is known as picric acid. Why picric acid is explosive?
Is phenol neutral to litmus? A) Red litmus paper : Litmus paper is used to distinguish acid from the base. Red litmus paper turns to blue in basic medium while remaining unchanged in acidic medium. Phenol is acidic in nature while ethanol is a very weak acid. It is almost neutral. Is ...
Explain why the -OH in acetic acid is acidic (will lower the pH in water) while the -OH in ethyl alcohol is not. Explain why salts can be acidic, basic, or neutral, and give examples. Explain why phenol is more acidic than cyclohexanol. ...
It can swap acidic H+ ions clinging to its surface for less acidic or basic cations (e.g., Ca2+), further lowering the H+ concentration and increasing the pH (Custos et al. 2020). In the present study, the translocation and com- partmentalization of metals and metalloids ...
Acidic Tyrode’s solution (Sigma) containing 0.2% PVA was used to remove the zona pellucida (ZP) from embryos before sample collection. Then, 30 ZP-free morula-stage embryos and nucleofected ESCDuxs were lysed in Lysis Solution (from SuperPrep II Cell Lysis & RT Kit, TOYOBO), directly. ...
But, heavy metals are potent inhibitors of photosynthesis as they can replace or block the prosthetic metal atoms in the active sites of certain enzymes. Likewise, the acidic functional groups of bacterial cell walls can also bind significant concentrations of aqueous cations, which can affect th...
With rising global temperatures, permafrost carbon stores are vulnerable to microbial degradation. The enzyme latch theory states that polyphenols should accumulate in saturated peatlands due to diminished phenol oxidase activity, inhibiting resident mic
Plastics and resins made of BPA weaken, and thus leach more BPA when they are old and wearing out, heated or frozen, washed with detergents, and exposed to oily or acidic foods and liquids. Thus, BPA leaching is especially a concern with canned foods, which often are oil-based and/or ...
Why ionization constant of phenol is higher than ethanol? Phenol are more acidic than ethanol because of stabilize of phenoxide as compare to ethoxide ion. Which is more acidic phenol or ortho methyl phenol? When an H+ ion leaves phenol, it forms a phenoxide ion, and the negative charge in...
