Most English words with the digraph ph come from Greek words; ph is the standard transliteration of the Greek letter φ (phi). The reason for this is that, in Ancient Greek, the letter φ was pronounced [pʰ], as opposed to π (pi), pronounced [p]. In English terms, that’s f, th and ch (like in loch or Baruch, not child).

The name, in both the forms Stephen and Steven, is commonly shortened to Steve or Stevie. In English, the female version of the name is “Stephanie”. Many surnames are derived from the first name, including Stephens, Stevens, Stephenson, and Stevenson, all of which mean “Stephen’s (son)”.

Wh represents the voiceless consonant corresponding with w, and is pronounced by emitting the breath sharply between the lips. It is a mistake to assimilate the sound to that of f in English, though this has become favourable in recent years with some of the younger Maoris.

The /f/ sound is usually spelled with the letter f, or ff if after a short vowel – this is covered in Unit 4. In some words, the /f/ sound is spelled using the digraph ph. These are often words from the ancient Greek language.

Digraphs ( ph, gh) as in alphabet, laugh. Digraphs consist of two consonants that are blended to make one sound. The digraph (ph) has the sound of (f).

The /f/ is a sound from the ‘Consonants Pairs’ group and it is called the ‘Voiceless labiodental fricative’. This means that you create friction between the bottom lip and top teeth. To produce the sound rest your top teeth on you bottom lip and force air out between your teeth .

The pH of a solution is a measure of the concentration of hydrogen ions in the solution. A solution with a high number of hydrogen ions is acidic and has a low pH value. A solution with a high number of hydroxide ions is basic and has a high pH value.

Originally Answered: What is the lowest value of pH? Since pH is defined as minus the logarithm of a number whose value is between 0 and 1, theoretically, the lowest value of pH is zero (0), which means a hydrogen ion activity of 1, which means basically that hydrogen ions (i.e. protons) are all that is present.

Even in pure water ions tend to form due to random processes (producing some H+ and OH- ions). The amount of H+ that is made in pure water is about equal to a pH of 7. That’s why 7 is neutral. In pure water near room temperature, the concentration of H+ is about 10-7 moles/liter, which gives a pH of 7.

The pH scale ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic. A pH greater than 7 is basic….

Most fruits and vegetables, soybeans and tofu, and some nuts, seeds, and legumes are alkaline-promoting foods, so they’re fair game. Dairy, eggs, meat, most grains, and processed foods, like canned and packaged snacks and convenience foods, fall on the acid side and are not allowed.
