As the ph approaches 14 what happens to the concentration of h3o+ ions

The concentration of hydronium ions decreases when an acid is diluted because on adding water the H+ ions of the acid and hydroxyl ions of water react to form water molecules and the concentration of hydronium ions decreases. When an acid is diluted, then the concentration of hydronium ions decreases.The pH scale is based on the concentration of H3O+ ions in a solution. In water, the concentration of H3O+ is balanced by an equal concentration of OH- ions. Hence, its pH is neutral. An acidic solution has a higher concentration H3O+ ions than OH- ions. A basic solution has a higher concentration of OH- ions than H3O+ ions. If, for instance, the pH of the blood and external fluid is too low (too many H + ions), then an excess of H + ions will enter the cell and disrupt normal chemical processes. In order to maintain the proper chemical composition inside the cells, the chemical composition of the fluids outside the cells must be kept relatively constant.

If we wish to find the hydronium ion concentration ([H 3 O +]) and the pH of a solution, we need to know both the strength of the acid (or base) and the concentration of the acid (or base). We will find that we need to treat strong acids (and bases) differently than weak acids (and bases) based on the extent to which they react with water.

The measurement of the hydrogen ion concentration (or pH) at each point in the titration allows us to find the location of the equivalence point, that volume of base which reacts completely with the unknown concentration of acid. It is at this equivalence point that the amount of base added is chemically equal to the amount of acid present. Answer: 1 📌📌📌 question 2.

Dec 09, 2008 · first of all. remember pH+pOH=14. for acid:0<pH<7 (find pOH=14-pH),for bases 7<pH<14. so. if you add more HCL to a solution ,you are actually adding more ions of H+(acid properties) as you know acid have pH<7 so you are reducing the pH by adding H+. The Ph will keep decreasing till it will become close to 0 (0<pH acid<7).
