What is the examples of metals used in electroplating?
The examples of metals used in electroplating are Chromium and Lead.
Is iron a anode or cathode?
it is an anode
What kind of sign does anode has?
An anode is positive, Cathode is negative. As such, an anode would usually be denoted as + If that is what you meant.
Which electrode in the anode is galvanic cell?
Zinc is the anode.
The anode in an electrochemical cell has this charge?
The Anode in electrochemical cell has negative charge (-ve).
Why do you use antimonial lead in chromium plating?
we use antimonial lead in chromium plating because if we use chromium as anode in the process, the number of anions will become more than that of cations.i,e cr++ in solution,cr+++ in anode,H+ in aquous solution of chromium sulphate and only two cations(so4-- and OH-) will be there to neutralize it.so one anion will exceeed in number and chromim could not be oxidized completely for plating.. tht is why antimonial lead is used as anode which is an inert anode an does not oxidizes but only passes electricity.
Is ectroplated gold is a pure gold?
Elctroplated gold is gold plating on other metals. The object shines and looks as gold because of the gold plating. Anode and cathode are used for gold plating.
What does an anode do?
apprently it attracts corrosion so it saves the head or block from corroding. the anode corrodes instead.
What is the examples of metals used in electroplating?
The examples of metals used in electroplating are Chromium and Lead.
What types of anode?
the two types of anode is stationary anode and rotating anode
Why are bath fittings coted with cromium?
Chrome plating (less commonly chromium plating), often referred to simply as chrome, is a technique of electroplating a thin layer of chromium onto a metal or plastic object. The chromed layer can be decorative, provide corrosion resistance, ease cleaning procedures, or increase surface hardness. Sometimes a less expensive imitator of chrome may be used for aesthetic purposes.Chrome plating a component typically includes these stages:Degreasing to remove heavy soilingManual cleaning to remove all residual traces of dirt and surface impuritiesVarious pretreatments depending on the substratePlacement into the chrome plating vat, where it is allowed to warm to solution temperatureApplication of plating current for the required time to attain the desired thicknessThere are many variations to this process, depending on the type of substrate being plated. Different substrates need different etching solutions, such as hydrochloric,hydrofluoric, and sulfuric acids(also called sulphuric acid ). Ferric chloride is also popular for the etching of Nimonic alloys. Sometimes the component enters the chrome plating vat electrically live. Sometimes the component has a conforming anode made from lead/tin or platinized titanium. A typical hard chrome vat plates at about 1 mil (25 µm) per hour.Various linishing and buffing processes are used in preparing components for decorative chrome plating. The overall appearance of decorative chrome plating is only as good as the preparation of the component.[1]The chrome plating chemicals are very toxic. Disposal of chemicals is regulated in most countries.Some common industry specifications governing the chrome plating process are AMS 2460, AMS 2406, and MIL-STD-1501.
The grid in a high-vacuum triode is usually kept negatively charged with respect to the cathode so that the electrons may be?
A grid in a high-vacuum triode is usually kept negatively charged with respect to the cathode so that the electrons may be passed through to the anode, but controlled by changes in grid voltage. The triode accomplishes this by amplifying signals applied.
In a simple cell the cathode or the anode is more reactive?
Anode(:

Why anode and cathode rays do not get neutralized?
There is no such thing as anode rays!!
