Document Summary
The ph of water is 7. 00 at 25oc and 6. 13 at 100oc. These data indicate that, in water, the acidity of water increases as temperature increases. [h3o+] increases as temperature increases both the acidity and [h3o+] increase as temperature increases the acidity decreases as temperature increases. Consider the following acids and the statements that follow. Acrylic acid and 2-nitrophenol are both strong acids. 2-nitrophenol is a stronger acid than acrylic acid. The ph of a 0. 010 mol l 1 acrylic acid solution is greater than 2. The ph of a dilute solution of hbr is 6. 98 at 25 oc. (assume that hbr is 100% ionized. ) Kw = 1. 0 10 14 ph + poh = 14. 00. With the assumption that hbr is 100% ionized in aqueous solution, what is the ph of. The conjugate base of a weak acid is .
