The capacity of a buffer to neutralize added acid or base depends on the concentrations of HA and A⁻ in solution. For a given ratio of [HA] to [A⁻], the greater the concentrations, the higher the overall buffer capacity. When [HA] is greater than [A⁻], the capacity is higher for added base than acid. When [A⁻] is greater than [HA], the capacity is higher for added acid than base. View more lessons or practice this subject at www.khanacadem...

thank you so much. had a confusion for long time, but its clear now.
Superb! I understood everything. Thank you❤
Master in engineering knowledge here💯💯🇺🇸
Is the addition of 0.0200 a constant one in adding a change in both buffer?😅 thank you
this was really helpful !!
This is probably useful, but make it more easier.
What program or app do you use for these videos? Love the writing and graphics.
Could you make videos on vapor pressure.
❤❤❤
Yay a new vid
👋👏👏

Work with Helen Howard pratea on google if you are finding it difficult , she is an expert advisor
BUFFER CAPACITY IS ANOTHER FORM OF DETEREOATION CONERING MOLECULAR ISOTOPES
What if the moles of acid is greater than the moles of OH- ? The acid would be completely used up, aka have 0 moles, and the ratio of weak base to weak acid would be 0... and log0 doesn't work.

Air pollution is responsible for 5 million deaths each year
Air pollution - the combination of outdoor and indoor particulate matter, and ozone - is a risk factor for many of the leading causes of death including heart disease, stroke, lower respiratory infections, lung cancer, diabetes and chronic obstructive pulmonary disease (COPD).
The Institute for Health Metrics and Evaluation (IHME) in its Global Burden of Disease study provide estimates of the number of deaths attributed to the range of risk factors for disease.1
In the visualization we see the number of deaths per year attributed to each risk factor. This chart is shown for the global total, but can be explored for any country or region using the “change country” toggle.
Air pollution is one of the leading risk factors for death. In low-income countries it tops the list. In 2017, it was responsible for an estimated 5 million deaths globally. That means it contributed to 9% - nearly 1-in-10 - deaths....

It's completely wrong. The concentration of CH3COO- after addition of OH- is 0.270 + 0.25 not 0.27 !!!!!
