<span>An acid is a compound that produces hydrogen ions when dissolved in water. The pH of acid is less than 7 because it is rich in H+ concentration. Basic solutions have pH greater than 7 because it is rich in OH-. Neutral solutions meanwhile have pH equal to 7.</span>

Answer: a. acid

Explanation:

a. Acids are those substances which either donates hydrogen ions $(H^+)$ when dissolved in water or accepts a pair of electrons.

$HCl\rightarrow H^++Cl^-$

b. Buffer is a solution which resist changes in pH on addition of small amounts of acid or base into it.

c. Bases are those substances which either donates hydroxide ions $(OH^-)$ when dissolved in water or donates a pair of electrons.

$NaOH\rightarrow Na^++OH^-$

d. Indicators are chemical compounds which show a change or appearance in color at particular pH. Example: litmus

Answer:

The orbital shapes are actually representation of (Ψ)2 all over the orbit simplified ... ψnlml(r,θ,ϕ)=Rnl(r)Ymll(θ,ϕ) , ... and thus it is directly linked to the angular and radial nodes. ... for different quantum values(which can be assigned to different orbitals are ) .... The two types of nodes are angular and radial.
