colorless crystalline solid that dissolves in water to give colorless solutions. It is classified as a dicarboxylic acid. In terms of acid strength‚ it is much stronger than acetic acid. Oxalic acid is a reducing agent and its conjugate base‚ known as oxalate (C2O42−)‚ is a chelating agent for metal cations. Typically‚ oxalic acid occurs as the dihydrate with the formula H2C2O4·2H2O. Oral consumption of oxalic acid or prolonged skin contact is dangerous. Malic acid is an organic compound with the formula

Which Substitute For Watering Plants Is Better? I. Introduction A. Background of the Study Plants are organisms that grow and reproduce their own kind. They need for‚ air‚ soil‚ water‚ light‚ and space to grow. Plants need soil. Water and minerals are taken from the soil through roots. Soil also provides support for the plant and an anchor for the roots to grow in. Decaying plants and animals leave behind minerals in the soil that are essential for future plant growth. Plants need

Experiment # 8 Qualitative Analysis of Cations Objectives Part I: Separate a mixture of known cations: Pb2+‚ Fe3+‚ Al3+‚ Cu2+‚ and Ca2+ into individual ions. Perform a series of tests to become familiar with reactions characteristic of each cation. Part II: Separate and identify individual cations in an unknown solution containing a mixture of up to five cations. Use information gathered in part I to identify the cations. Introduction Qualitative analysis is a general name for the process

The result of a sodium/potassium electrolyte ratio of less than 25:1 along with increased levels of BUN‚ calcium and creatinine and a decrease in blood glucose and albumin concentrations may lead to a diagnosis of Addison’s disease. However‚ since electrolyte levels may not affect Addison’s disease an ACTH stimulation test provides a definitive diagnosis by

Ferric Oxalate Trihydrate and The Determination of Oxalate Ion in Ferric Oxalate Trihydrate using Titrimetry Abstract: In this two-part lab‚ we will learn about coordination compounds and their uses with stoiciometry. We will also find out about how theoretical yield is calculated from a reaction we will create. We will also synthesize Potassium Ferric Oxalate Trihydrate (K_3 [〖Fe(C_2 O_4)〗_3]•3H_2 O) using a two step reaction. In the second part of this lab we will calculate how much Oxalate Ion
