The correct answer is (b) 2. The pH scale is used to measure how acidic or basic a solution is.pH and pOH: Crash Course Chemistry #3036 related questions found Is pOH of 14 a strong base? pH of 7 is neutral. pH of 8-10 is a weak base/alkali. pH of 11-14 is strong base...
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...

basic concentrated hematite suspensionTemperature dependency of pH of concentrated metal oxide suspension, containing acid or base, was used as a method for determination of total enthalpy of surface reactions. This enthalpy depends on pH due to electrostatic interactions. It is sum of standard (...
The acidic for the basic nature of a solution can be determined by finding the pH of the solution. We can apply the following formulas to find the pH of the solution. If pH<7, the solution will be acidic. If pH=7, the solution will be neutral. ...
Calculate the pH and identify the acidic or basic: {eq}\displaystyle \rm [H_3O^-] = 3.4 \times 10^{-3} \ M {/eq} Acidic, Basic, and Neutral Solution: To decide whether a solution is acidic or basic or neutral, we need its {eq}p\rm{H}{/eq} value. ...
exhibit basicity under appropriate conditions. However, compared to its acidity, the basicity of Phthalimide is relatively weak. The main reason is that imide acid (acidic form) is a more stable form than imide base (basic form). Therefore, under neutral pH conditions, Phthalimide tends to exhib...
Now you know how to tell if your pH level indicates your body is acidic or basic. But what's the difference between an alkaline versus acidic pH, really? First, an acidic pH: If you know you're acidic, it can indicate an underlying disorder like acidosis, according to the StatPearls ar...
