hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!

connectedness in handwriting analysis is a useful tool in establishing the writer’s method of thinking and its perception in where he/she fits in to the environment around him in the social sense. in addition, the more connected the writing of an individual, the more he/she is flexible and single minded.
