Rubbish. The pH of pure water is always 7. Sadly, drivel in the first sentence makes one wonder whether it is worth reading any more.

No.
It falls from about 7.5 near freezing to about 6 near boiling.

It doesn't help to add to puppypower's nonsense.

Not a lot of biology occurs in ice or steam.

Very little of it occurs at 25C; probably even less at pH7

But the word "always" is one to be careful about.

Try 37C and pH 7. Just the right ambient to fertilise a mammalian ovum. Okay, it's a small thing, but the beginning of a whole lot of biology.

Almost the whole of biology isn't to do with mammals. None of it has to do with pure water.
While estimating the average number of legs on an animal (or its pH)  is interesting, it won't detract from the fact that this

The pH of pure water is always 7.

is flat out wrong because of the temperature dependence.

That doesn't make the OP right, it just puts you both in the same category,

Re."estimating the average number of legs on an animal is interesting". To the nearest integer lots of people when asked will think it's roughly 4 because they think of cats + dogs + horses etc.. Some will think there's lots of birds.
The clever ones think about insects.
The very clever ones know it's zero.
There's a lot of nematodes out there.

The hydrogen bonding matrix of liquid water, alters water in many different ways such as the pH affect

Rubbish. The pH of pure water is always 7. Sadly, drivel in the first sentence makes one wonder whether it is worth reading any more.

The hydrogen bonding matrix of liquid water, alters water in many different ways such as the pH affect and 3-D water polymers. In fact, H2O molecules to not exist more than a tiny fraction of a second before the atoms are swapped out.

I quoted myself above and I never claimed any value for the pH of water at any conditions. I was characterizing the pH affect of water, in general, as being due to hydrogen bonding. Hydrogen bonding is also responsible for the extended structuring of water, in water. The binary nature of hydrogen bonding; polar and partial covalent, allows the hydrogen bond to act as intermediary; step down or step up, for the covalent bonds of water; O-H, so they can become less covalent and more polar, or reverse.

What we measure as the pH is not the same as the atoms of water exchanging partners, so no water molecules has the same oxygen and hydrogen partners for very long. This can occur with or without ionization, since it only requires the nonbonding orbitals become bonding via a hydrogen bond and the bonding orbitals become nonbonding. Again oxygen is dealing with the octet can accommodate up to four hydrogen.

Water is at maximum density at 4C.  When water is close to boiling, the density is lower. Higher density at 4C means a shift to polar hydrogen bonds, while lower density is heading more toward the covalent side.The slight acid near boiling, by being connected to the lower density covalent aspect, means oxygen is holding electron tighter, so H+ can leave; slight  acid.

At near freezing or at 4C  water is denser and hydrogen bonds are more polar. Now oxygen contributes more electron density to all the hydrogen, to get a slight negative charge or slight alkalinity. This is useful, but not needed where I was going.   

Water expands when it freezes, which means the maximum density at 4C becomes very low density at 0C over just a few degrees. There is an abrupt shift in oxygen from polar toward the covalent side, so the crystal matrix of ice can share in extended 3-D easier.

When water gets to the boiling point, the density also goes down. This is why hot water can freeze faster than cold water; Mpember affect. The expanded hot water, when chilled quickly, can continue its covalent nature directly into freezing and expansion, and skip the polar intermediate step that cold water has to take.  All water anomalies and properties can be explained with the  binary hydrogen bonding switch analysis

The oxygen at the boiling point of water; water vapor, controls the electrons more than in liquid water, since there is no longer be any external hydrogen bonds with other water molecules, so oxygen has to accept extra electron density.

This unique state is useful for forming clouds via a strong polar attraction in an oxygen state that would be more covalent in the liquid state. The binary switch is sort of stuck in a middle option, that give clouds and weather, some extra dynamics. The polar state is more electrostatic, while the covalent state of more magnetic. This middle state of the switch, for water vapor, has both attributes; oxygen is more covalent/magnetic and hydrogen is more polar/electrostatic. It can't become a binary switch, until the liquid state forms so there is external hydrogen bonding.

The Miller Experiments used hot water vapor and other gases thought to be present in the early earth atmosphere. Miller started with the oxygen of water having to hold the octet electrons, stronger, with hydrogen more positive, as seen in the updrafts of thunderclouds. This positive water is not exactly a dipole in this state. Miller was able to form a wide range of amino acids, as well as oils and tars of complex composition from simple gases using the more reactive hydrogen protons of the middle switch.

Lightning and thunder appears when it is raining or water is condensing into liquid, allowing water to change into the binary switch, with the release of energy. This energy can amplify depending on the rate of condensation. Miller picked a sweet spot in terms of a water transition with punch.

the pH affect of water,

That is meaningless so

I was characterizing the pH affect of water, in general, as being due to hydrogen bonding.

Is also meaningless.

Puppypower,
if we just tell you that we already knew that water is weird, will you stop banging on about it?

I will take this as saying "no".

At near freezing or at 4C  water is denser and hydrogen bonds are more polar. Now oxygen contributes more electron density to all the hydrogen, to get a slight negative charge or slight alkalinity. This is useful, but not needed where I was going.   

Water expands when it freezes, which means the maximum density at 4C becomes very low density at 0C over just a few degrees. There is an abrupt shift in oxygen from polar toward the covalent side, so the crystal matrix of ice can share in extended 3-D easier.

Why?
Why do you keep restating the obvious (badly)?
