To create a solution with a pH of 4 using vinegar, you can mix approximately 1 part vinegar with 10 parts water.
PH4 could refer to phosphine, which is a chemical compound with the formula PH3. It is a colorless, flammable gas.
The oxidation number of PH4 cannot be determined because phosphorus (P) does not have a fixed oxidation number in this compound.
The bond angle in PH4 is higher than PH3 because PH4 has a tetrahedral molecular geometry with bond angles of about 109.5 degrees, while PH3 has a trigonal pyramidal molecular geometry with bond angles of about 107 degrees. This difference in bond angles is due to the presence of an additional hydrogen atom in PH4 compared to PH3.

PH4 has sp3 hybridization. This means that the phosphorus atom forms four sigma bonds using one 3s orbital and three 3p orbitals.
The pH level of boric acid is typically around 5.0 to 6.0 in water. It is considered a weak acid.
When mixing a solution at pH 4 with a solution at pH 8, the final pH will be between 4 and 8. The resulting pH will depend on the ratios of the two solutions being mixed. If equal volumes are mixed, then the final pH will likely be around 6.
Any acid solution with 1.00*10-4 mol/L H3O+
PH2, known as phosphine, is a weakly acidic compound. In water, phosphine can react to form PH4+ and OH- ions, indicating its weak acidic nature.
pH4 refers to a specific level on the pH scale, which measures the acidity or alkalinity of a solution. A pH of 4 indicates that the solution is acidic, as it is below the neutral pH of 7. Common substances with a pH around 4 include vinegar and some fruit juices. This level of acidity can affect chemical reactions and biological processes in various contexts.
The pH value of acid rain typically ranges from 4 to 5.6.
NOT LEMON JUICE (PH4/5) BUT SOMETHING MEDIUM HMMM.... WATER ---- Pure, distilled water. I can prove this as well, because all acids contain hydrogen ions; all alkalis contain hydroxides. Therefore when an acid reacts with an alkali, this general formula takes place: H+ + OH- -------- H2O. Magic, no?
