pH - Basic (alkaline) vs. Acidic Introduction to pH - the acidic and basic (alkaline) definition. pH can be viewed as an abbreviation for power of Hydrogen - or more completely, power of the concentration of the Hydrogen ionin a liquid. The mathematical definition of pH is a bit less...

Indicate whether the following substance is acidic, basic, or neutral. Soft drink, pH 2.8 pH: One can easily state conclusion regarding a chemical substance's nature (if its neutral/acidic/basic) on the basis of its known pH value. Some pH values for acidic sub...
pHrodo dye is an aminorhodamine pH indicator that increases in fluorescence as the pH of its surroundings becomes more acidic (Figure 20.4.1). The amine-reactive succinimidyl ester form of the dye (P36600) provides access to a wide variety of user-defined bioconjugates by following t...
Intracellular pH in tumor cells is normal or slightly alkaline; in contrast, extracellular pH, which varies with the type of tumor, is usually acidic. Intracellular pH has been shown to be alkaline in cancer cells [3]. Rich et al. [4] noted that the intracellular pH was approximately 0.4...
If the acid is strong but the base is weak, the aqueous solution of the salt will be acidic. If the acid is weak but the base is strong, the aqueous solution of the salt will be basic.Answer and Explanation: Aluminum nitrate (Al(NO3)3) is a salt...
Acids produce H+ ions in aqueous solutions while bases accept H+ ions as well as produce OH- ions in aqueous solutions. In other words, acids are viewed as electron pair acceptors and bases as electron pair donors. Every liquid has either acidic or basic properties. A liquid that is anaci...
Typically, acidic or basic standard solution was loaded into the syringe and injected into 8 mL of each stock solution via pumping (WH-SP-02, Suzhou Wenhao Microfluidic Technology Co., Ltd.) at a constant rate (200 μL/min). Real-time pH value was recorded every minute by pH meter (...
