10 mM tartaric acid (sodium) buffer solution (pH=4.2)
Tartaric acid (M.W.=150.09)..........................2.5 mmol (0.375 g)
Sodium tart rate dihydrate (M.W.=230.08)........7.5 mmol (1.726 g)
Add water to make up to 1 L.
10 mM tartaric acid (sodium) buffer solution (pH=2.9)
Tartaric acid (M.W.=150.09)..........................7.5 mmol (1.13 g)
Sodium tartrate dihydrate (M.W.=230.08)........2.5 mmol (0.58 g)
Add water to make up to 1 L.
PH5 doesn't actually exist as a stable molecule. However, if one imagines it to have the same geometry as PF5 (namely trigonal bipyramidal), then by symmetry PH5 would be non-polar.
It will go down by 1 or 2 i think because water is pH 7 and pH7-pH5=2
PH5 does not exist. If it did, the bonds would possible be polar as there is an electrnegativivty difference between P and H. PH3 does exist and will have bond polarity.
Yes
pH3. It is more acidic

Yes
be quiet this question is stupid
