Yes if u add 2 acids or bases or and acid and base together if both contain acids or bases it creates a poisounos gas that can kill or knock you out and will make pH higher. Dont try it though buy pH paper and use on ammonia ammonia is about a 11-12 on pH scale its very powerful. that was extra but yes it can cause sudden change matter what acids or bases you combine it with.
it is false because a buffer solution always form by the mixture of weak acid and weak base
A buffer solution contains both a weak acid and its conjugated weak base in a normal ratio between about 1 to 10 and 10 to 1. So the buffer solution consist of weak acid and its salt or a weak base and its conjugated acid.

Dangerous weather conditions can be indicated by sudden visual changes in the clouds, a strong movement of wind or other sensations. Some people can even feel pain in arthritic joints as pressure changes occur.

Buffers are weak acids or bases that can react with strong acids or bases to prevent sharp, sudden changes in pH....

Negative feedback mechanisms work to prevent sudden severe changes within the body.
The level of pH (potential of Hydrogen) is very important for maintaining our lives and well-being. For example, the normal pH for our blood is between 7.35-7.45 (an average of 7.4), any deviation from this very small range could mean serious trouble. For this reason we emply buffer systems. Buffer is a substance that counteracts changes to the pH level. Examples for the buffer systems are: - Phosphate buffers - bicarbonate buffers - protein buffers (like haemoglobin).

A buffer solution.
A buffer solution might be acidic, alkaline or even neutral. The only special feature of these solutions is the resistance of buffers to change their pH value. Let us consider the acetic buffer, which is acidic, and made out of acetic acid and sodium acetate. When little alkali is added, it would be neutralized by the protons from the acid and become to a new equilibrium to cancel the effect of alkali. When a little acid is added, the protons in the added acid along with the acetate ions in the buffer, would make acetic acid molecules and achieve a new equilibrium. This aspect can be easily understood by the Le Chatelier's Principle.
It is called an exclamatory sentence.
