Which buffer solution comprising of the following has its $$pH$$ value greater than 7?

Protons ( $$H^+$$ ions ) are found when a substance is dissolved in water. The substance is ___________.

Which among the following resists a rapid change of pH?

Addition of water to $$X$$ solution will not change concentration of $$H_{3}O^{+}$$. $$X$$ is:

Assertion: $$NaCl(aq)$$ is an electrolyte.
Reason: It forms ions in solution.

$$\displaystyle { H }_{ 2 }O+{ H }_{ 2 }O\rightleftharpoons { H }_{ 3 }{ O }^{ + }+{ OH }^{ - }$$
The above reverse reaction is an exothermic reaction. What will happen if the temperature is lowered?

The Haber process is used for producing ammonia from nitrogen and hydrogen. This reaction could be forced to produce more ammonia by :

__________ can be shifted by adding more reactants.
