Question

Recall that all aqueoous solutions contain_____. Water can also undergo ____. This process is called the ______of water. The reaction can be written as:

Notice the double arrow in the reaction. This indicates that the reaction is_____. However, only a tiny fraction of water molecues ionize at any one time.The concentration of ions has been determined(experimentally). In purewater, the concentration of H2O is ____.
A substance can be described as acidic ifthereis ahigher concentrationof______ comparedto _____.
A substance can bedescribed as basic if there is ahigher concentration of_______compared to _______.

Again none of this is in my textbook:((

Answer 1

Recall that all aqueoous solutions contain_"solute ions, H^+ ions/OH^- ions/whatever"____. Water can also undergo ___"ionization"_. This process is called the __"autoionization"____of water. The reaction can be written as:
"2H2O <==> H3O^+ + OH^-"

Notice the double arrow in the reaction. This indicates that the reaction is_"reversible"____. However, only a tiny fraction of water molecues ionize at any one time.The concentration of ions has been determined(experimentally). In purewater, the concentration of H2O is "about 55.5M"____. "H^+ = OH^- = 1E-7M at 25C"
A substance can be described as acidic if there is a higher concentration of__"hydronium ions or H3O^+"____ compared to "hydroxyl ions or OH^-" _____.
A substance can be described as basic if there is a higher concentration of_"OH^- or hydroxyl ions"______compared to "hydronium or H3O^+ ions" _______.
