Example Problem 1 - Calculating the pH of a Strong Acid-Strong Base Solution 350 ml of a 0.02 molar solution of NaOH is added to 500 ml of a 0.03 molar solution of HCl. Calculate the pH for the final solution. Step 1:Identify the acid and base in the solution. Acid-HCL, B...
d) Strong acid + weak base in water.Classify the acid and base as either a strong acid (SA), weak acid (WA), a strong base (SB), or weak base (WB): KOH.Classify the acid and bas...
This paper presents the solution to a calculationof the pH of a very dilute solution of a strong acid orbase, taking into account the effect of the hydroniumor hydroxyl ions generated from the ionisation of thestrong acid or base on the ionisation of water, as asecond very weak acid. To...

In cases where the base releases hydroxide ions, these ions bind to free hydrogen ions, generating new water molecules.Figure 1. The pH scale measures the concentration of hydrogen ions (H+) in a solution.The stronger the acid, the more readily it donates H+. For example, hydrochloric acid...
The devastating damage of strong base is because phospholipids, which form cell membrane and nucleic membrane, are broke down by hydroxyl ions. Base hydrolysis causes the saponification reaction. Thus decomposition of membrane aggravates mortality of cells. Figure 2 The damage of hydroxyl and hydrogen...
For example, shale and coal are rich in sulfates and can produce a strong sulfuric acid that will lower pH. On the other hand, limestone (calcium carbonate) produces a basic solution when mixed with water to increase the pH. In a like manner, the topography and type of soil affect the ...
the number of added protons (H+) or hydroxide ions (OH-) depends only on the amount of strong acid or strong base that is added and not on the pH of the environment. But most acids and bases we will deal with in brewing, especially when we talk about the effects of pH, are weak...
The buffering capacity of each buffer was calculated according to the Van Slyke buffer capacity (β) equation [28,29]:(3)β=−dAdpHorβ=dBdpHwhere A and B are the number of moles of strong base and strong acid, respectively [30]. 2.15. pH variation in buffered medium Firstly, the ...
