So at room temperature, the pH and pOH are both 7. This means that in a neutral solution [H+] and [OH-] are in a 1:1 ratio
Hydroponics is more than just another way to grow plants–the technology has the potential to change how we engage with food cultivation as a whole! For the first time since humans started tilling the land, modern hydroponics technology frees us from the soil beneath our feet, allowing us to bring food production indoors where we can layer in additional climate and lighting controls. The result is an ability to grow food anytime, anywhere in the world.
Answer:
bleaching powder is actually a mixture of calcium chloride, calcium hydroxide and calcium hypochlorite. hence it is not a single salt. It is not completely soluble in water as it composed of heavy calcium salts, which are known to be insoluble in water.
For [Ca +2 ]:
0.0010 mol/l · 0.05 l =
For [ SO4 -2 ] :
0.01 mol/l · 0.05 l =
Cumulative volume:
50 ml + 50 ml = 10 ml = 0.1 l
[Ca +2 ] =
[SO4 - 2] =
Qc for CaSO4:
Qc =
This is less than Ksp of CaSO4.
Answer:
C ) No precipitation will occur.
The enol carbon or ∝-carbon nucleophile attacks at molecular bromine in the acid-catalyzed α-bromination of a ketone
Treatment of ketones with bromine in the presence of acid will results in formation of a new C-Br bond at the alpha position. The purpose of the acid is to catalysed formation of the enol from ketone , which is active nucleophile in the reaction. This reaction is called haloform reaction which is used to identify the methyl substituted ketone in the presence of aldehyde.
