A32.00 ml sample of an unknown h3po4 solution is titrated with a 0.110 m naoh solution. the equivalence point is reached when 24.83 ml of naoh solution is added. what is the concentration of the unknown h3po4 solution? the neutralization reaction is
h3po4(aq)+3naoh(aq)→3h2o(l)+na3po4( aq)

Concentration of in sample is 0.25 M.

Explanation:

From the reaction, one mole of reacts with 3 moles of NaOH.

Now, number of moles of NaOH, n =

Therefore, mol of NaOH reacts with .

So, concentration of

Therefore, concentration of in sample is 0.25 M.

Hence, this is the required solution.

answer: option (4) is the correct answer.

explanation:

areas which are at low altitudes and near the equator tend to receive direct sunlight from the sun. hence, heat energy or radiations from the sun make these areas warmer and they have warmest water.

whereas areas which are at high altitudes and away from the equator do no receive direct sunlight. hence, no direct contact from the sun makes these regions colder and thus, they have colder water.

thus, we can conclude that the statement areas at low latitudes near the equator have the warmest water because they receive the most direct sunlight best explains the relationship between an area's geography and the temperature of its surface water.
