Question

Ca3(po4)2—h3po4—kh2po4—k2hpo4—k3po4

Answer 1

Ca3(PO4)2 + 6HCl = 3CaCl2 + 2H3PO4
KOH + H3PO4 = KH2PO4 + H2O
KOH + KH2PO4  = K2HPO4 + H2O
KOH + K2HPO4 = K3PO4 + H2O

Answer 2

The chemical equation you provided seems to represent a series of reactions involving different phosphate compounds and phosphoric acid. Here's an explanation of each component:

Ca3(PO4)2: This compound is called calcium phosphate. It is a common inorganic compound that consists of three calcium ions (Ca2+) and two phosphate ions (PO43-). It is often found in minerals and serves as a source of calcium and phosphate.

H3PO4: This is the chemical formula for phosphoric acid. It is a strong acid that consists of three hydrogen ions (H+) and one phosphate ion (PO43-). Phosphoric acid is widely used in various industries, including food production and rust removal.

KH2PO4: This compound is called potassium dihydrogen phosphate. It is a salt that contains one potassium ion (K+) and one dihydrogen phosphate ion (H2PO4-). It is commonly used as a fertilizer and as a pH buffer in laboratory settings.

K2HPO4: This compound is known as dipotassium hydrogen phosphate. It contains two potassium ions (K+) and one hydrogen phosphate ion (HPO42-). It is also used as a pH buffer and as a source of potassium in fertilizers.

K3PO4: This compound is called potassium phosphate. It consists of three potassium ions (K+) and one phosphate ion (PO43-). Potassium phosphate is used in various applications, including as a food additive and as a buffering agent in the pharmaceutical industry.

The chemical equation you provided represents a series of reactions where the phosphate compounds and phosphoric acid are potentially reacting with each other or undergoing different transformations. However, without specific information about the reaction conditions or the purpose of the reactions, it is difficult to provide a more detailed explanation.
