c and d
H₃PO₄ : Phosphoric acid
KOH : Potassium hydroxide
K₃PO₄ : Tripotassium phosphate
H₂O : water
<h3>Further explanation</h3>
Given
Reaction
H₃PO₄ + 3 KOH → K₃PO₄ + 3 H₂O
Required
Type of reaction
General equation
Name of reactants and product
Solution
Double replacement reaction : Cations and anions of different compounds switch places
It can also be said as <em>a neutralization reaction</em> because it produces water(reaction between an acid and a base)
AB + CD ⇒ AD +CB

H₂O : water
Answer:
None
Step-by-step explanation:
A high pH is caused by an excess of hydrogen ions over hydroxide ions.
Hydrogen ions are so small that they pass through the pores of an ordinary filter.
Thus, ordinary filtration has no effect on the pH of water.
Answer:
In aqueous solution the pH scale varies from 0 to 14, which indicates this concentration of hydrogen. Solutions with pH less than 7 are acidic (the value of the exponent of the concentration is higher, because there are more ions in the solution) and alkaline (basic) those with a pH higher than 7. If the solvent is pure water, the pH = 7 indicates neutrality of the solution
Explanation:
PH is a measure of how acidic or basic a liquid is. Specifically, from a dissolution. The acidity of a solution is essentially due to the concentration of hydrogen ions dissolved in it. In reality, the ions are not found alone, but are in the form of hydronium ions consisting of one oxygen molecule and three positively charged hydrogen. PH precisely measures this concentration. And to do it, we can use simple and very visual methods.
Physical weathering occurs when rock is broken down through mechanical processes such as wind, water, gravity, freeze-thaw cycles, or the growth of roots into rock.
