The value for kw is 1.0 x 10-14 at 298k, but this value is temperature dependent. given what you know about kw and acid/base chemistry, what will the ph of water be at 303k if the value for kw is 1.47 x 10-14? is this solution acidic, basic, or neutral?

The pH of the water will be 6.92 and the solution will be neutral.

pH value determined how basic or acidic a solution is.

The meaning of pH is potential hydrogen.

By the formula:

Thus, the pH will be 6.92 and the solution will be neutral.

6.92; neutral

Explanation:

Kw = [H^+][OH^-] = 1.47 × 10^-14

pKw = pH + pOH = 13.83

At neutrality, [H^+] = [OH^-] and pH = pOH

2pH = 13.83

 pH =  6.92

The pH will be 6.92.

At 303 K, this will be the neutral pH, because [H^+] = [OH^-]

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.

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
