Adecrease of one unit in the ph scale above represents a tenfold increase in the hydrogen ion concentration of a solution. for example, a solution having a ph of 4 is 10 times more acidic than a solution with a ph of 5. if acid precipitation rain changes the ph of a pond from 7.5 to 6.5, the level of hydrogen ion has changed by a factor of

Consider two solutions: solution x has a ph of 4; solution y has a ph of 7. from this information, we can reasonably conclude that consider two solutions: solution x has a ph of 4; solution y has a ph of 7. from this information, we can reasonably conclude that the concentration of hydrogen ions in solution y is 1000 times as great as the concentration of hydrogen ions in solution x the concentration of hydrogen ions in solution x is 1000 times as great as the concentration of hydrogen ions in solution y solution y has no free hydrogen ions (h+) the concentration of hydrogen ions in solution x is 3 times as great as the concentration of hydrogen ions in solution y

Ph is a logarithmic scale used to indicate the hydrogen ion concentration, [h+], of a solution: ph=−log[h+] due to the autoionization of water, in any aqueous solution, the hydrogen ion concentration and the hydroxide ion concentration, [oh−], are related to each other by the kw of water: kw=[h+][oh−]=1.00×10−14 where 1.00×10−14 is the value at approximately 297 k. based on this relation, the ph and poh are also related to each other as 14.00=ph+poh the temperature for each solution is carried out at approximately 297 k where kw=1.00×10−14. part a 0.35 g of hydrogen chloride (hcl) is dissolved in water to make 2.5 l of solution. what is the ph of the resulting hydrochloric acid solution?
