- Calcium is a ________ cation. a)monovalentb)trivalentc . . . - EduRev
Calcium is a divalent cation because it has a charge of +2 In order to understand why calcium is a divalent cation, let's break down the concept of cations and valence Cations: - Cations are positively charged ions, meaning they have lost one or more electrons - They are formed when an atom loses electrons, resulting in a net positive charge
- The hardness of a water sample is measured directly by . . . - EduRev
The hardness of water is defined as the concentration of multivalent metallic cations which destroys the surfaced property of soap (concentration of ions) which reacts with Soap and leads to the formation of a precipitate Ca2+, Mg2+ are major constituents A1+3, Sr3+, Fe2+ Cu2+ are minor constituents of hardness Hardness is classified into two categories: Carbonate hardness and non-carbonate
- Which of the following is required for microinjection method of gene . . .
Micro-injection method is the direct or vectorless method of gene transfer, in which foreign DNA is directly injected into the nucleus of animal cell or plant cell by using micro-needles or micro-pipettes

- Which of the following cations impart(s) pseudohardness to water - EduRev
These cations are typically sodium (Na+) and potassium (K+) Explanation Calcium and Magnesium Calcium (Ca2+) and magnesium (Mg2+) are the primary contributors to the hardness of water When water contains high concentrations of these cations, it is classified as hard water
- In the cubic packed structure of mixed oxides, the lattice is . . . - EduRev
This represents the ratio of cations to anions in the cubic packed structure of mixed oxides Therefore, the correct answer is option B) X4Y5O10 In the cubic packed structure of mixed oxides, the lattice is made up of oxide ions, 20% of the tetrahedral voids are occupied by divalent X2+ ions and 50% of the octahedral voids are occupied by
- Gene Cloning Chapter Notes | Biotechnology for Class 12 - EduRev
Extraction media typically use a mild alkaline pH buffer (0 05 M ionic strength) with EDTA to chelate divalent cations (e g , Mn²⁺, Mg²⁺), preventing nuclease activity and salt formation with nucleic acid phosphate groups SDS, an anionic detergent, makes proteins anionic, dissociating them from nucleic acids and inhibiting nuclease activity

DMT1: Proton-coupled transporter (Nramp2) for Fe²⁺ and other divalent cations (Zn, Mn, Co, Cd, Cu, Ni, Pb) into enterocytes Ferroportin 1: Basolateral transporter for Fe²⁺ exit Hephaestin: Facilitates ferroportin 1, not a transporter itself
- Atomic Structure Chapter Notes | Chemistry Class 8 ICSE PDF . . . - EduRev
Depending on the number of electrons donated, elements are called monovalent (Na⁺), divalent (Mg²⁺), or trivalent (Al³⁺) Did You Know? All metals and hydrogen have positive valency because their valence shells have 1 to 3 electrons Valency and Symbol of Some Common Cations Formation of Electronegative Ions:
