Any acid solution with 1.00*10-4 mol/L H3O+
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 strength of an acid or base is measured on a logarithmic scale, meaning a change of 1 pH unit represents a tenfold difference in acidity or basicity. Therefore, a substance with a pH of 9 is 1,000 times stronger in basicity than a substance with a pH of 4.
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.
The pH level of boric acid is typically around 5.0 to 6.0 in water. It is considered a weak acid.
To create a solution with a pH of 4 using vinegar, you can mix approximately 1 part vinegar with 10 parts water.

Since the conjugate acid is supposed to be just the addition of an H+, then it should be either HPH3+ or PH4+, phosphonium cations, resulting from protonation of phosphine. It has a molar mass of 35.01 g/molThe (positive) cations are much like the analogue ammonium ions NH4+.
