Answer: 1and 4
Explanation: iron is an element not an alloy. An ionic lattice is not bonded covalently.
PH measures the concentration of hydrogen ions on the log 10 scale. Thus, a pH 5 solution has 2 order of magnitude difference from that of pure water, which has a pH of 7.
Therefore,
. A solution of pH 5 has 100 times more hydrogen ions that that of pure water.
