The relative amounts of hydrogen and hydroxide ions determine whether an aqueous solution is acidic, basic or neutral. true or false

True

Explanation:

The amount of Hydrogen ion and hydroxide ion determines the acidity or alkalinity of an aqueous solution.

The higher the hydrogen ion content the higher the acidity of the solution. The increase in the amount of the hydrogen ion brings about decrease in the pH scale. The pH scale of about 0 - 2 has a very high hydrogen ion contents and as the Hydrogen ion decreases the pH value increases.

The higher the hydroxide ion contents the higher the alkalinity . The increase in the amount of hydroxide ion brings about increase in the pH value. The pH value of 12 - 14 depicts very strong alkalinity content. As the hydroxide ion increases the pH value increases.

If the hydroxide ion and hydrogen ions are of equal proportion the solution becomes neutral. The pH value for neutrality is 7.  

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).
