"WebpH is a representation of hydrogen ion activity in a liquid. It is the negative logarithm of the number of hydrogen ions (in moles) per liter of liquid. Thus: 10 -11 moles of hydrogen ions in 1 liter of liquid = 11 pH. 10 -5.3 moles of hydrogen ions in 1 liter of liquid = 5.3 pH. " - How does a difference in 1 ph unit change

WebA buffer has its highest capacity at equal concentrations of weak acid and conjugate base, when pH = pKa . WebThe addition of water plus baking soda will alters the pH of weak acid/ base and make them more alkaline. This is because baking soda is very alkaline in nature. Hydrogen ions in water will add the concentration of hydrogens in weak acid/bases. Baking soda increases the pH of weak acid and weak base. Hope this helps you :)
