1. Acid , H+ ion
2. Base , OH- ion
3. Base , OH- ion
4. Acid , H+ ion
Answer:
Reaction
Explanation:
A reaction that is spontaneous at low temperature
Firstly calculating number of moles of hcl disssolved. The answer would be in the pic above. Concentration of hydrogen ions can be calculated by using that mole amount dividing by 3litres of solution to get 0.003196. Hence the ph of solution will be -log10(h+ concentration) which is equal to 2.495
Move the decimal 4 times to the right than thay number tomes 10^-4
